At Apple's last event, Steve Jobs called the iPod touch the company's "most popular iPod," and it's easy to understand why. In just a few short years, the iPhone-with-no-phone has kept in lockstep with Cupertino's halo device, benefitting from the same kind of constant hardware and software updating that has helped turned the iPhone into an iconic gadget. The touch has been right alongside the iPhone's meteoric rise in popularity, becoming the go-to second-pocket slab for millions. There are good reasons, too. Apple boasts about gaming on the device -- claiming it beats out both Nintendo's and Sony's offerings in sales... combined. While we can't concede that the device is a dedicated game console, it most definitelygames. And it's still an iPod, an internet device, and a thousand other things thanks to Apple's vastly populous App Store. Now the player has once again reaped the rewards of iPhone updates, boasting a new Retina Display, the A4 CPU, two cameras which allow for FaceTime calling and 720p video recording, and all the new features of the company's latest mobile operating system, iOS 4.1. But despite all of the plusses, we still have to ask: is the little do-everything box still worth the premium price tag? We took a deep dive on the latest model and have the verdict, so read on to find out.
If you own the last version of the iPod touch, the design of the latest version shouldn't come as a major surprise. Instead of aping the iPhone's new glass-sandwich looks, the touch hews close to its roots with a super thin profile made up of one part glass screen and one part all-metal back. The device still bears the smudge inviting chrome rear panel, and continues the trend of shrinking the thickness as far down as possible. We thought the iPhone 4 was crazy thin, but the new touch looks like a toothpick by comparison. In our large hands, we might even argue that it's a little too small -- but it should be just right for the legion of teens and tweens that will clamor for this come holiday time.
As with earlier version, hard buttons come in the form of a single home key, a power / sleep button (finally moved to match the iPhone's placement at the top-right of the device, as opposed to the opposite side on previous versions), and two volume buttons on the left. Around back there's now a small camera lens in the upper corner of the device, while a single, VGA shooter peers out from behind the glass on the front of the player. A quick note: we had a little trouble consistently finding the sleep button when using the device -- it's a bit buried in the housing.
All told, we think it's break even in the looks department. The thinness is certainly welcome, but not a game changer. While we like the iPod touch design overall, there's nothing present in the new version that makes it significantly more lust-worthy than previous generations.
Inside the new iPod touch is Apple's A4 CPU, the same engine used to power the iPhone 4 and iPad (and that new Apple TV as well). We assume the device is sporting the same 512MB of RAM that the iPhone has, but we won't know for sure until someone like iFixit gets their hands on it. The 3.5-inch capacitive touchscreen is called a Retina Display, which means it had equal resolution (960 x 640) and pixel density (326 ppi) as the iPhone 4, but it's not the same IPS panel that you're used to on the touch's big brother. What does that mean in real world terms? Well in our testing we could see noticeable difference in viewing angles, but only at pretty extreme positions. We also felt like the touch's display was slightly darker than the iPhone 4 screen. In general, we don't see this as a major detractor for the device, but there's no question that the iPhone 4 is sporting a qualitatively better display. It may be an "iPhone with no contract" in many regards, but not when it comes to the screen.
Aside from that you've got WiFi (802.11b/g/n to be exact), Bluetooth 2.1 + EDR, and Nike + support built in. No GPS here, and obviously no cell radios.
We're a little confused by Apple's reluctance to add a GPS chip to these devices. Since the App Store is litered with navigation software, and this could easily take the place of a TomTom or Garmin device, it seems like a short walk to paradise for the company. The touch checks a lot of boxes on the list, but true navigation is still blank, and we can't really understand why.
Just like Apple wanted, much has been made about the touch's camera capability. It seems like the idea of a touch with cameras has been a long time coming (and based on what we've seen from case manufacturers since the last fall Apple event, we're actually about a year behind schedule). But the cameras on this device aren't quite the same pair that you get on the iPhone 4, and there should be no mistaking one for the other. The rear camera on the device is capable of 720p video, but that means that its maximum resolution is 1280 x 720 -- and when it's used for still photos, that resolution becomes 960 x 720 (that's a 720p at a 4:3 ratio). Obviously this is not the same lens or sensor as the iPhone 4, and when we asked Apple about it, they said it was more a consideration of size rather than cost. According to Greg Jozwiak, using something closer to the iPhone 4's sensor would have made the casing for the touch considerably larger. The camera is also fixed-focus rather than auto-focus, which means that tapping on the screen has no discernible result except for altering the white balance and exposure. Oh, and there's no flash to be found. Around front, the phone sports a VGA camera (similar to that of the iPhone), but again this is a fixed-focus lens.
We really would have liked to see a higher quality shooter on the back of this device -- maybe the iPhone 4 has spoiled us, but even something like 3 megapixels wouldn't have felt out of place here. And we're pretty sure Apple could figure out a way to keep this thing thin and light in spite of it.
In our side by side shots with the iPhone 4, it's obvious that the touch's performance for still images is far below that of its big brother. For taking quick shots (which don't require tight focus), you'll be fine, but if you want to grab printer-ready pics, the touch definitely will not be a reasonable stand-in. However, when it comes to video, the 720p performance was actually quite surprising, and the device seemed to have no problem capturing smooth HD content. See the clip below (and check the raw file here) for a look at what kind of results it can produce.
As with the new nano, the touch did seem to sound a little better than previous versions, but it's not such an astounding difference that you should toss your last gen model in the garbage. Overall, playback seemed solid to us -- at least it didn't leave us wanting for quality. If you're planning on using the external speaker for listening, however, you might want to reconsider. We can't remember the last time we heard something so tinny. Of course, it's not surprising considering the size of this housing. Even though it's located in a similar spot as the iPhone 4's speaker, the volume and quality of audio it produces is not even in the same vicinity. Still, how often will you use this?
If you've used an iPhone or iPod touch with iOS 4, there will be few (if any) surprises here. The touch performs exactly like any other iOS device, though admittedly you'll probably notice faster performance if you're upgrading from an earlier model of touch. Our review unit was loaded up with 4.1, which means we had access to a non-beta Game Center, as well as some of those proximity and performance fixes Apple told us would be coming -- though without seeing 4.0 on this device, it's hard to spot the differences.
Overall, performance was silky smooth on the touch -- games didn't lag, and getting around in the OS was as painless as it is on the iPhone 4. Multitasking worked flawlessly, and for those of you using the device heavily as a media player, it makes juggling playback functions along with the other "stuff" the touch does dead simple.
The new touch does come equipped with FaceTime, though now instead of using your phone number (and SMS) to connect, it asks for your email address as an identifier. Unfortunately, only other 4.1 devices can make a connection with the touch, so we were only able to make a handful of calls. In general, the application worked as effortlessly as it does on the iPhone, though we still had some freezes and breakups even on our strong WiFi connection. Ultimately, we still see this as a side dish and not the main course for these devices. With the iPhone 4, we complained that without 3G options for FaceTime calls, the feature remains limited in use, and that's now doubly true with the touch -- unless you're carting around a MiFi, you're stuck mostly indoors (and probably at home) for these calls. One thing to note about FaceTime on the touch -- on our device the volume seemed extremely low even when cranked up (in keeping with our experience for music playback), though the New York Times' David Pogue told us his device sounded loud and clear. "Like an iPhone," he said.
As we said, Game Center is installed on the device, but no games seem to take advantage of the feature just yet. We did field a few friend requests, but all we could do was look at our list of contacts. We'll likely take a longer look at this feature when it's accessible to all iOS 4 users, but for now the most notable thing about the app is that Game Center looks nothing like any Apple product you've ever seen. That font!
Reading through this review, it should be clear that there isn't actually a whole lot to say about this device that hasn't already been said. The new touch isn't magical or revolutionary, or even unfamiliar. What it is, however, is a product without a peer; a media player that does far more than media playing. Besides the smaller screen real estate, the touch might be better compared to a tablet or netbook -- it has many of the same functions (more, in some cases). So you're not just dropping $229 (8GB), $299 (32GB), or $399 (64GB, also, ouch) on a music and video player -- you're buying into a mini-computer, a video camera, and a game system all with a massive ecosystem.
If you're already carrying around a smartphone with the above functions, maybe the iPod touch doesn't make sense, but for the legions of buyers out there who have yet to make the jump (or are stuck with an outdated handset), this device's appeal is hard to deny. Don't get us wrong, the touch isn't without faults -- the lack of GPS and a fairly low-quality still camera come to mind -- but there's nothing major here that gives us pause (and frankly, nothing else like it on the market). With the addition of HD video shooting, the new Retina Display, and a faster A4 processor, the touch has just gone from "nice to have" to nearly irresistible.
Hardware
As with earlier version, hard buttons come in the form of a single home key, a power / sleep button (finally moved to match the iPhone's placement at the top-right of the device, as opposed to the opposite side on previous versions), and two volume buttons on the left.

All told, we think it's break even in the looks department. The thinness is certainly welcome, but not a game changer. While we like the iPod touch design overall, there's nothing present in the new version that makes it significantly more lust-worthy than previous generations.
Internals
Aside from that you've got WiFi (802.11b/g/n to be exact), Bluetooth 2.1 + EDR, and Nike + support built in. No GPS here, and obviously no cell radios.
We're a little confused by Apple's reluctance to add a GPS chip to these devices.

Wrap-up
If you're already carrying around a smartphone with the above functions, maybe the iPod touch doesn't make sense, but for the legions of buyers out there who have yet to make the jump (or are stuck with an outdated handset), this device's appeal is hard to deny. Don't get us wrong, the touch isn't without faults -- the lack of GPS and a fairly low-quality still camera come to mind -- but there's nothing major here that gives us pause (and frankly, nothing else like it on the market). With the addition of HD video shooting, the new Retina Display, and a faster A4 processor, the touch has just gone from "nice to have" to nearly irresistible.
So we just got our hands on the new iPod touch... and boy is it small. As you would expect, the functionality of the device is identical to the iPhone 4, as well as the functions of the cameras. In essence, it's a much thinner iPhone 4, with no cell radio and a lower quality still camera. The design is relatively in keeping with previous touches, so no major surprises there, but the inclusion of that A4 chip, higher resolution screen, and front and back cameras makes it a far more versatile device. Take a look at the gallery below if you're wondering just how much of a sliver this is -- it makes the iPhone 4 look... fat.
Update: It's worth noting that the back camera is clearly not the same 5 megapixel shooter present on the iPhone 4, as the specs on Apple's page for the touch list the still photo resolution at 960 x 720 -- a huge difference.
We knew this was coming and here it is: the Netflix application, heretofore reserved only for iPad users, has trickled down to iPhone and iPod touch devices. Version 1.1.0 makes the TV show and movie streaming app universal -- so long as your universe is known as iOS -- and looks to massively expand the available audience for Netflix's mobile effort. What are you waiting for, go get it already.

If flicking through that puny pop-up tray isn't what you had in mind when you envisioned multitaskingiPhone, well, you're not alone. But jailbreakers can get gorgeous Exposé-style task management with Multifl0w 2.0. Here's how it works: on your
It's pretty simple:
1. Jailbreak. If you haven't upgraded to the latest, jailbreak-breaking iOS 4.0.2 on your iPhone, or 3.2.2 on your iPad, then jailbreaking with jailbreakme.com is still easy as pie. Just visit the site on your iPhone or iPad and follow the simple steps. There's no jailbreak available for iPhone 4's running 4.0.2 yet, but one's bound to pop up sooner or later.
2. Buy multifl0w 2.0 from the Cydia App Store. Multifl0w, which costs $5, has long been a staple of pre-iOS4 (read: jailbroken) iPhone multitasking, but a recent update adds the super sexy Exposé-style management seen in the clip above. You can customize the trigger for activating the Exposé, and, crucially, you can customize just what type of multitasking you want it to trigger. From the Multifl0w FAQ:
How does Multifl0w incorporate with Apple's multitasking on iOS4?
This was a difficult problem to solve, because there are so many different possible solutions. So what's the answer? Provide as many different customization options as possible so that it's easy for everyone to have the backgrounding style they want. Multifl0w used in conjunction with Backgrounder should be able to provide you with the options that suite your preferences. Using Multifl0w without Backgrounder on iOS4 will function like Apple's switcher, apps stay "open" in memory (although not actually running). Using Multifl0w without Backgrounder on 3.1.x is not advised, because apps will be closed as soon as they are exited. However, Multifl0w does not force Backgrounder to be installed on any OS version for maximum flexibility.
Can I use both Multifl0w and Apple's switcher together?
Yes, you can. Just set Multifl0w's activation method to something other than Double-Press Home, and you will still be able to use both together.
The developers note that the Exposé-style multitasking will work on older iPhones and iPod Touches, though it really requires the speedy processors of the iPhone 4 and iPad for the full, smooth experience. [Multifl0w - Thanks Ryan94]
Complete feature guide to Apple’s latest iOS 4
iOS 4 (previously iPhone OS 4 or iPhone 4.0) continues Apple’s relentless yearly mobile OS update cycle. If 2007 was the mainstreaming of the multitouch user interface, 2008 all about the App Store, and 2009 was filling in the feature list, then iOS 4 promises to be… well, that’s why we’re here.
(And yes, iOS. That’s the new name Apple has licensed from trademark-holders Cisco to represent the iPhone, iPad, and iPod touch — and maybe soon the Apple TV and who knows what else — family.)
Back on April 8 at the sneak preview event, Apple promised 7 “tent-pole” features and 100+ general user features overall, along with 1500 major new API for developers. We’re going to walk you through the ones that matter most.
Note: this is an updated version of our original beta walkthroughs, based on the GM (gold master) seed released at WWDC 2010. If anything changes in the general release slated for June 21, we’ll update again.
(For more on the hardware, see our iPhone 4 preview.)
iOS 4 in 10 minutes: video quick-start guide
If you don’t have time (yet) to read this massive iOS 4 walkthrough and are eager to get the basics down now, here’s a quick 10 minute video guide to get your started.
We’re showing it off on an iPhone 3GS, which should be similar to how it will work on an iPod touch G3. If you’re using the iPhone 3G or iPod touch 2G you won’t get the multitasking and wallpapers. You’ll blame Apple. Apple will blame the hardware. The hardware will try to frustrate you into upgrading to an iPhone 4. You’ve been warned.
Note: If you haven’t updated yet, save yourself some time and potential hassles and go read our getting ready for iOS 4 post first first. Then once you’re good to go, sit back, relax, and hit play on the video below.
What Hasn’t Changed
As always, we’ll start off by telling you what hasn’t change so we can clear the deck for what has. For more information on any functionality that’s pretty much identical to past versions, check out our previous walkthroughs:
And here’s a quick list of the unchanged apps in iOS 4:
- Stocks: Similarly, Stocks got landscape and a slew of swipe-able data last time, so the update love gets skipped this time.
- Weather: Almost comedically at this point, it’s still unchanged from iPhone 1.0. Still no HTC TouchFlo 3D style animations, no landscape mode with more/different information. Not even a Calendar-style icon update to show current local weather. Nada.
- Voice Memo: Introduced in iPhone 3.0, it looks pretty much the same in iOS 4.
- Clock: With nothing but a lap feature added last time, we lose the “but” and keep the “nothing” for iOS 4.
- Calculator: Upgraded back in 2.0 for landscape scientific mode, all Calculator gets this time is a slight icon tweak towards the red.
(We’re not counting getting a resolution bump for iPhone 4 Retina Display as a functional change.)
System-wide enhancements
Spell check
Combined with the iPhone’s existing — and industry leading — predictive auto-correct, it’s a powerful combination.
Text Replace
Additionally, if iOS 4 autocorrects a word and you immediately backspace, a popup will appear offering to replace the correction with the originally typed word.
VoiceControl
Wi-Fi
Virtual Keyboard
Instead of just hitting the globe key to cycle through languages on the virtual keyboard, you can now hold it down to get a popup showing all currently enabled international keyboards.
Bluetooth Keyboard Support
Over-the-air Carrier Setting Updates
Based on reports from Rogers/Fido users in Canada, iOS 4 adds the ability for Carrier Setting Updates to be pushed out over-the-air (OTA) to iPhones and installed on-device. (In previous versions iTunes would handle the update and sync it over).
Home Screen
(If you get a new iPhone 4, or do a clean install of iOS 4, you’ll also note Clock, Compass, Calculator, and Voice Memos have been moved to a Utilities folder by default — more on Folders later).
In addition to the iPad wallpapers, Apple has also introduced a few new ones, all seemingly focused on livening up the home screen without being too visually distracting. Natural textures and muted patterns get an obvious focus here with stones, rocks, and textiles front and center.
(See all of them in our iOS 4 wallpaper gallery)
In addition to previous status icons, the top bar will now show a north-east pointing arrow to alert you that location-based services (GPS) are being used. (So you’ll see this in Maps and when using navigation, location-based social networks or games, etc.) An orientation lock icon will also show if you’ve enabled the widget to lock your screen in portrait mode (see below).
The color bands indicators across the top of the screen that highlight running voice or data connections (green for Phone, red for Voice Memo, blue for tethering) get expanded. Red now serves double-duty to indicate a VoIP app (like Skype) is active in the background.
How the SpringBoard has been once again extended to visualize new, core-level OS changes is where things get more interesting…
Spotlight
Multitasking
Why no iPhone 3G? Apple abjectly refuses to put their name on an implementation where hardware constrains software — see video recording last year — and that means iPhone 3G isn’t up to their multitasking standards.
As to how it works, instead of a traditional “leave full apps running in the background” approach, Apple instead chose to implement a more restricted but, they felt, better performing and power friendly solution involving 7 specific background API (application programming interfaces.)
Local notifications
In addition to the existing push notification service from Apple’s servers, which provide sound, badges, and alert popups for everything from IM to game challenges, iOS 4 adds local notifications so something like an alarm-clock app could register an alert that would sit in the iPhone in the background until the proper time, then activate. That takes the online server out of the equation which is good for tasks that don’t need additional information from the cloud, and so don’t have to activate the radios.
Task completion
There’s another API for task completion so that, for example, if you’re uploading a picture to Twitter and leave the app, it can register a thread to keep uploading the picture in the background while you do something else. That means the entire app doesn’t have to keep running, freeing up memory and lightening battery load, and even the thread will terminate when the upload is done.
Fast task switching and saved state
Fast task switching deals with the perceptive speed that multitasking offers. With previous versions of iOS, if you left an App Store app it would shut down completely. If you went back — regardless if it was a second or a week or later — it would usually restart not from where you left off but from the beginning. A few developers tried to add persistence on their own, saving your place when you came back as best as previous OS versions allowed, but most didn’t — especially games which was aggravating when phone calls pulled you unexpectedly out of them. Also, if you closed one app and went to another, you could theoretically be stuck swiping back or forth between 11 home screen pages.
Saved state is now built into iOS 4. If you switch out, Apps have their currents state saved to memory and if/when you go back, the app checks the memory save and resumes from that state. [Thanks Aaron]
To enable fast app switching, Apple’s created a new UI mechanic. Now, when you double tap the home button, the screen turns translucent and slides up, allowing you to peek at the apps running “under the hood”. (Technically frozen with state saved and threads registered with the background API).
Apps in the fast switcher UI are sorted in order of last usage. That means, if you’re moving between a set of commonly used apps, they’re most likely right next to each other and not screens and screens away. These two elements combine together to make launching apps perceptively much faster, even though the apps don’t have to be running in the background consuming resources just for that convenience.
Positionally the fast task switcher apps take up the space traditionally reserved for the Dock, so while it’s a tad confusing the concept of apps at the bottom of the screen being more permanent and easily accessible remains. Behaviorally, while they look like a secret dock, they function like the Home Screen itself in that you can swipe from right to left to scroll through a several 4-icon sets of multitasking apps.
Given even the iPhone 3GS has only 256MB of RAM, we assume Apple will discretely kill off the least-used app in the stack when things get tight. Whether or not that means the icon disappears from the multitasking UI we don’t know, but worst case you just have to go to the home screen, re-launch it (hopefully from saved state) and all you notice is a slightly longer start up time. iPhone 4 is supposed to have 512MB of RAM which should allow for significantly more threads to run in background without slowdown or other problems.
iOS 4 helps users visualize what’s going on when switching tasks by introducing a new, carousel-like animation. The new animation occurs when you switch between two apps either via the new, double-click-Home to trigger to launch the multitasking UI, or when one app calls another app (i.e. when you’re in Contacts and you tap to send a contact an SMS).
Launching or leaving an app retains the same, zoom-based effect as always (though the wallpaper in iOS zooms slightly as well, like on the iPad).
Interlude: Task Killing
At the iOS 4 event, Steve Jobs likened task managers (in the multitasking, not to-do sense) to styluses — if you need them there’s something wrong. Initially this created confusion in iOS 4 when it was noted, if you hold your finger down on multitasking apps, they’d jiggle and bring up a delete icon that, if tapped, removed them.
It appears like there’s a couple things going on. First, with built-in Apple apps, like Mail, if you “delete” it from the fast task switcher, you will still receive Mail (it doesn’t kill the background thread that checks, sounds/vibrates, and updates the badge) but the app seems to do some sort of data cache refresh at times.
For App Store apps, if you “delete” them it does appear to force a reset when next you launch them, i.e. they won’t resume from the previously saved state and their threads seem to be restarted. [Thanks Justin!]
Widgets
Just like to the left of the main home screen is a special Spotlight screen, to the left of the fast app switcher is a special widget dock containing an software version of the iPad’s hardware orientation lock control (though it currently only locks in portrait mode). More over, there are three circular controls to skip back, play/pause, or skip forward any music (including streaming music) — and rewind or fast forward if you hold them down. Lastly, whichever app is currently playing the music, be it iPod, iTunes (streaming podcasts, for example), or an App Store app (like Pandora or Slacker) is shown at the right so you can jump back to it and access further controls.
The presentation may not be as visually slick as Palm webOS’ Card view (which looks like iPhone Safari’s Page view) or Mac OS X Expose mode, but it keeps tens of millions of existing iPhone and iPod touch users grounded in the interface they’re familiar with and that’s what Apple is prioritizing.
Note: Previously you could assign the double-click home button action to trigger Phone Favorites, Camera, or Spotlight. On iPhone 3G under iOS those options remain. On iPhone 3GS under iOS, in early betas you could double-click-and-hold the home button to trigger Phone Favorites, but this function doesn’t appear to have survive to the final release. Hopefully something will replace it and soon.
Background music, location, and VoIP
Speaking of streaming music, perhaps most famously, Apple is allowing apps to register three specific types of the threads for persistent backgrounding (they can just keep running until you close them). Again, this isn’t the whole app running, just one thread from the app, so the idea is it won’t slow down performance, use up memory, or drain battery to the same degree. These API are for streaming music, location, and VoIP (voice over IP).
This means you can listen to Pandora, Slacker, etc. while surfing the web. Navigon, TeleNav,TomTom, etc. can keep using the GPS and alert you to directions while you’re on the phone, and to further save resources, non-critical location apps like FourSquare, Gowalla, Loopt, etc. can be alerted when you change cell towers. Fring, Skype, Line2, etc. can answer calls and receive messages when you’re not in the app, making them more equal telephony citizens.
What’s still missing are background API for timeline updates, so that IM, Twitter, RSS, etc. could update like Mail does and have new messages ready and waiting when you return to the app. Also, there’s no API to let internet sessions like SSH, RDP/VNC remain active when you exit an app making it more onerous for network administrators and others to manage remote machines. Hopefully these can be added in future revisions.
Folders
Enter Folders. A Folder is simply a grouped icon that holds up to 12 other icons inside it. (And for those keeping count at home, the new math means a whopping 2016 apps can be kept available at once. Shudder).
The way it works is you tap a Folder icon and once again the Home Screen fades and splits open, this time below the Folder. Inside the split are all the apps contained in the group.
To create a Folder, you begin by tapping and holding an icon to put it in jiggly mode, just like you did before to delete or move it. Then, drag it over and drop it on top of another icon to create a Folder. (This works better when icons aren’t at the right edge of the screen, as the move behavior seems to supersede the Folder behavior, causing the icon to wrap to the next line before you can drop on top of it.) Once created, iOS reads the apps’ category data and tries to name the folder for you, but you can easily edit it and change it to anything you want.
To remove apps from a Folder, put them in jiggly mode inside the Folder and drag them out (or just delete them if you don’t want the app anymore at all). You can also move them around within the Folder to customize their order.
Folders can be put in jiggly mode and moved as well, but not deleted (they can only be deleted by removing all the apps from within them, and which point they self-destruct for you). You can even move them to the Dock, which means you could have 48 apps readily available at any time for quick launching.
And while you still can’t delete Apple’s built-in apps, you can take the ones you’re not using and hide them away inside a folder so they waste as little Home Screen space as possible (as Apple now does by default with the Utilities folder mentioned previously).
Again, not as visually exciting perhaps as Mac OS X’s Stacks, but it keeps current iPhone users in a familiar interface while adding much-needed functionality.
The ability to manage Folders has also been added to iTunes 9.2, mirroring the creation, editing, and removal features found on-device. 
Messages
Messages (finally) gets a character counter so you’ll know when you’re getting close to, or going past, the SMS limit (which would cause a second message to be sent). It kicks in after you’ve typed 50 characters or so. [@iMuggle]
iOS 4 will now put an exclamation badge on the Messages app as a way to inform you when an SMS text or MMS multimedia message fails to send.
There’s also a new API to allow in-app SMS for developers who want to include the functionality in their own apps. While this might be similar to the iPhone 3.0 embedded email option, and whether or not it will let users reply to SMS without leaving an app, it doesn’t seem as elegant a solution as a global background messaging system.
Calendar
First, you can now show all or hide all calendars or individually check/uncheck just the calendars you want to see.
Birthday calendars have also been added to the option, something that was previously only possible to see under certain setup conditions.
Lastly (and most excitingly), Apple has finally added Calendar access for developers. What this means is you may soon see apps where you can buy tickets for a local movie and have the show time automatically added to your Calendar.
Photos
If you have a Mac with iPhoto ‘09 and you’ve let it automatically file your photos by time stamp (Events), through facial-recognition algorithms (Faces), and via geo-location (Places). All these join the previous Albums view to form the bottom tab bar.
Landscape mode is also now supported in album and gallery views [@antonioj].
Previous betas included a Rotate function under the action button that would turn a photo 90 degrees, but this doesn’t seem to have made it into the final. Hopefully it will return.
If you Email Photo, you now get the option of sending a small, medium, or large version (shrunken pixel dimensions and hence file size), or at actual size.
Lastly, developers have been given access to the photo and video library (not just the image picker as in previous OS versions).
Camera
Still photography maintains its leg up, however, via a new 5x digital zoom. When you tap the screen, a slider pops up allowing you to swipe to the right to increase magnification and swipe left to decrease.
With iPhone 4, there’s an additional control to swap between the beefed up 5mp back-facing camera, and the all new front-facing VGA camera (if you want to take a self-portrait/profile picture). There’s also an icon to show the new rear-mounted LED flash. This feature sounds like it’s automatic for still but can be turned on and left on for night-time video shooting, but we’ll have to wait and see when iPhone 4 ships.
Developers also get full access to and control of video playback and recording.
YouTube
Maps
For developers, overlays can now be added to embedded maps to show extra data like routes or annotations.
Notes
(UI-wise this is similar to how you back out/left in Calendar or Contacts to toggle data sources.)
The way these show up in Mac OS X is via the built-in Mail.app client in the Notes tab.
On Gmail they show up as a generic label. In other IMAP clients, regardless of OS, they’ll show up as generic IMAP folders.
iTunes Store
In iOS 4 it’s rock solid. You can scrub and it re-buffers and keeps playing flawlessly. You can stop it and come back hours or even days later — even after using the iTunes app to search for other things or the iPod app to play different audio — and it still knows where you left off and starts playing again instantly without missing a beat.
As mentioned previously in the multitasking section, when iTunes is using the background music streaming API (I’m assuming thats’ what it’s using) it gets the widget position in the fast task switcher interface, complete with widget controls.
Settings
General: Network
You can now choose to not only turn off 3G data or roaming data, but all cellular data.
General: Location Services
At the iOS event, Apple made a big deal about user privacy when it came to location (like a shot at Google). That manifests here with far more granular controls over which apps are allowed to access your location data (GPS, Wi-Fi mapping, and cell tower triangulation) and the aforementioned north-east pointing arrow that shows up when any app has used your location in the last 24 hours.
General: Spotlight Search
Since double clicking the home button is now a hard-wired to launch the fast-task switcher for iPhone 3GS and iPhone 4, the Home Button setting is gone and replaced by direct access to Spotlight Search preferences. 
Since iPhone 3G won’t be getting multitasking those options remain under iOS 4 for that device.
General: Passcode Lock
Previously available only through an Enterprise profile, iOS 4 brings stronger, alphanumeric passcodes to all iPhone users. That means you’re no longer stuck with only a 4 digit pin, but can now create longer passcodes with far greater variation. Of course, longer, more varied passcodes are more of a hassle to remember and enter, but that’s the cost of good security.
Mail, Contacts, Calendars
As previously mentioned, Notes will now sync over IMAP and the settings for that appear here. First, all the way at the bottom, you can choose which account to use as the default for note sync.
Inside MobileMe, Gmail, or other IMAP accounts, you can choose whether or not to enable sync. Again, there’s no support for Exchange ActiveSync accounts yet (including Gmail via GoogleSync).
Safari
When you tap into the Safari’s URL bar in iOS 4 and start typing, Safari starts to do a “keyword search”, i.e. display predictive results based on your bookmarks and history. Anything that contains the text you’re inputing either in the URL or history is listed below the URL field so the moment you see what you want you can just tap it and go.
This makes it easier to find something if you don’t remember the exact web page address or if you know you recently saw a site, and know what it was about, but don’t remember where exactly it was. Just start typing a few words you do remember and let Safari do the heavy lifting. Highly convenient and certainly “awesome”. [To misappropriate the term from Mozilla]
Also, welcome to iOS search options, Microsoft Bing.
Messages
Here’s where you can turn on that new character count option.
iPod
The iPod app now has an overlay that shows you information about songs and podcasts. While functional it’s not terribly attractive so it’s nice to be able to toggle it off right here.
App Store
iAd
Functionally these are built in HTML5 (no Flash need apply) and seem to work as apps-within-apps. Tapping on a banner brings up a full-screen ad-as-webapp and examples shown included plenty of animated UI effects and content that ranged from videos to freebies like wallpaper, to free and paid apps you could download from within the ad (no trip to the App Store needed). An exit button is persistent at the top left so users can quit the add at any time.
Apple will be selling and serving the ads, so all we can do is hope they’re unobtrusive and actually reach the quality levels presented. For paid apps that also try to include in-app iAds, that bar will rightly be very, very high.
Quick Look
Accelerate
2000 hardware accelerated math APIs probably won’t be seen by users, but there’s not doubt we’ll feel them in the games. Zoom. Zoom.
File Sharing
Again it looks like the iPhone is finally getting in iOS what the iPad got in 3.2 with the file/document transfer feature now exposed in iTunes sync.
Now all we need is an elegant way to share and wirelessly sync those documents across multiple devices and users. MobileMe 2.0, souped up iWork.com 2.0, where are you?
Phone
The biggest addition to the iOS 4 Phone app is iPhone 4 exclusive — FaceTime. When connected to Wi-Fi and making a call to another iPhone 4 user, the Hold button gets replaced with a FaceTime video icon. (Where the hold option goes under these circumstances is as yet unknown.)
Tapping that initiates a FaceTime video call. During the FaceTime video call, the person you’re calling fill the screen, your own camera input is boxed in the lower left corner (you can touch and drag it to move it around), and mute, hang up, and switch camera buttons line the bottom of the screen. (Switch camera toggles between the rear-facing and front-facing cameras on the iPhone 4).
As with Calendars, Notes, etc. you can tap a button on the top left, in this case Mailboxes, to back into a selection screen where you can then go into All Inboxes, a specific account’s inbox (which is considered fast inbox switching), or into the complete folder and sub-folder system of a given account (how Mail has worked from iPhone 1.0 to iPhone 3.0).
Once inside, All Inboxes is visually indistinguishable from an account-specific inbox, it simply contains all of their messages.
What is distinguishable are the small carets (technically greater-than symbols) to the right of replies that indicate a message is part of a thread. A number, typically 2 or 3, accompanies the caret to indicate how many replies are in the thread.
Tapping on a message that’s part of a thread doesn’t take you to the message but rather to a second list-view, similar to the inbox itself, but containing only the messages from the thread. Tapping on one of them then takes you to the message. A thread view contains a small vertical bar at the top with the subject of the thread and time of the most recent reply. A button to the top left of the message that’s part of the thread also contains the subject of the thread and lets you back out and see the thread again. The button then switches to contain the name of the inbox so you can back out again, leave the thread completely, and see all your messages.
So yes, the tap, tap, tap of inbox navigation persists, albeit shifted from moving into and out of inboxes to moving into and out of threaded messages.
Like iOS 3.2 for iPad, you’ll be able to open email attachments in apps. Now there’s no iWork (Numbers, Pages, Keynote) for iPhone yet, but plenty of apps should support it as they push out the iOS 4 compatible versions.
Great news for heavy ActiveSync users, iOS 4 supports multiple accounts. So, for example, you can now have your work Exchange server and home Google account both set up to push through ActiveSync (which is what Google Sync users behind the scenes) at the same time. Win. Win.
Also for Gmail users, the Delete button has no been properly renamed as Archive (since Google really doesn’t want you deleting anything if they can possibly help it).
Lastly, in previous versions of the iPhone OS, when you wanted to abandon an email, you would hit Cancel and get options to Save (store the email in Drafts), Don’t Save (trash the email), and Cancel (go back to writing the email). The naming of these options was likely too confusing so in iPhone OS they’ve been replaced with a big red Delete button (to trash the email), Save as Draft, and Cancel. And yes, you can still cancel a cancel. (iPad, by contrast, still has Save and Don’t Save, but no Cancel since it’s in a popover rather than full-screen menu and you can just tap away to cancel).
Safari
While HTML5 video would work under iPhone 3.1.3, it would launch the full screen QuickTime player to do so. Under iOS, it seems to play in-line as well [MobileGeekdom], like it does on the iPad.
If history is any indicator, Apple will likely also integrate whatever advancements WebKit and the Nitro JavaScript engine make between now and release this summer. However, there’s no sign of Safari 5 desktop’s key new features — reader (think built-in Instapaper) and extensions.
iPod
Album art has been added to album views, jazzing up the track lists.
And in yet another iPad-like update, on-the-go playlists are dead, long live… just regular old playlists. You can add them via an item in the playlists list, at which point you get a popup that asks you for a name. Next, you tap on any songs you want to add, and when you’re done, you have a new playlist. If you’re not happy with it, or any playlist, just swipe to bring up the usual red Delete button and annihilate it.
Contacts
If you look at a linked contact, the header will show Unified Info at the top so you know it’s linked. At the very bottom of the contact it will show you the source of the links (i.e MobileMe, Google). Tapping on the source lets you see the original, non-unfied info from just that source.
If you don’t like the idea of your contacts being linked, you can tap edit and hit Unlink. If iOS 4 missed linking a contact that ought be linked, tap edit, scroll down to the bottom, tap Link Contact and choose the contact you want linked.
Game Center (Preview)
Game Center is Apple’s entry into the social gaming network space (think Xbox Live or Playstation Network for iOS devices). With Game Center you’ll be able to invite friends to play, use matchmaking to challenge other players, gain achievements, and have your scores displayed on a leader board.
Game Center won’t launch with iOS this summer, but is scheduled for release “later” this year.
iBooks
Apple has announced new features, including notes and bookmarks, and that those along with highlights will automatically be synced across all the iOS devices logged into your iTunes accounts. (So you can have the same book, at the same place, with the same annotations on your iPhone, iPod touch, and iPad).
Also, iBooks will be able to add PDFs to a second book shelf and open them in the same iBooks interface.
Due to the fracture and regionalism in books, it’s going to take Apple a while to get deals in place with all publishers in all areas which means most countries won’t have paid content at first, only public domain books from the Project Gutenberg library.
Accessibility
Bluetooth support has been extended to more than 30 braille devices with tables for more than 25 languages.
Touch Typing lets you run your finger across the keyboard, hear the letter you’re currently over, and release your finger to type it.
The basic rotor has been made visible so sighted users can see it in action, and you can now add custom settings to move through content.
iOS 4 pricing and availability
Apple has announced that iOS 4 will be coming to iPhone and iPod touch on June 21, and iPad later this fall. In a huge departure from previous years, Apple is also making it a free update to all users, iPhone and iPod touch alike. (If you have a compatible device, see directly below).
iOS 4 device compatibility
Before we begin it’s important to note that not all iOS 4 features will be available for all iOS devices.
- iPhone 4 (2010): All features
- iPad (2010): Coming this fall
- iPhone 3GS and iPod touch G3 (2009): No features requiring iPhone 4-type hardware (i.e. FaceTime)
- iPhone 3G and iPod touch G2 (2008): No multitasking, custom wallpaper, and Bluetooth keyboard support.
- iPhone 2G and iPod touch G1 (2007): not compatible/no update
Yes, the original iPhone 2G and iPod touch G1 don’t look to be getting iOS 4 at all — Apple considers them outdated. Second generation iPhone 3G and iPod touch G2 are getting the update but no multitasking — Apple doesn’t consider them powerful enough (similar to video recording last year). And it should go without saying only iPhone 4 (and perhaps a forth generation iPod touch when it ships this fall) will be able to use hardware specific features like the Retina Display resolution or the front-facing camera.
Additionally, Apple’s own iMovie for iPhone will only run on iPhone 4 — apparently it needs the A4 chipset — so there might be other apps that go 2010-only. Legacy, right?
Conclusion
Apple is again rounding out their offering with iOS 4, which is the sign of the maturity of the platform. Since they’ve stated several times now that they’re using the iPhone to “educate” users about multitouch interfaces, they’re going to continue keeping changes evolutionary for now, and the UI broadly consistent across devices. There won’t be any huge, revolutionary changes again until they have to, and they don’t have to yet. Restraint can be a virtue.
Some functionality is still not present, like non-interuptive notifications, widgets beyond the limited fast task switcher UI, wireless sync/sharing, less painful file round-tripping, etc. but Apple is no doubt working on this the way they worked on copy and paste and multitasking. The question is how and when, not if. After all, it’s only 9 or 10 months until the iOS 5 sneak preview in spring 2011, right?
But this is not a review — our full rundown of the pros and cons will come after the official launch, when we’ve had a chance to spend some quality time with the final version on the new iPhone 4 hardware.
Congratulations to the iOS team at Apple, phenomenal work. Again.
