You can find the Purchased list in the App Store's Updates section. It has two tabs - All and Not On This iPhone. It's the easiest way to again download an app that you purchased and uninstalled.
Note that this list is available on the iOS 4 as well.
Now let's talk about the Storage Management. You can find it in Settings->General->Usage menu. Here you now have storage information too, before the Battery Percentage toggle and the statistics.
The Storage part begins with Free and Used space info and then you have a list of your ten biggest apps and their memory footprint - usually the Music and some heavy games such as Infinity Blade. You can access all of your installed apps via the dedicated button at the end of the top 10 list.
The Storage settings • managing an application
Tapping on an app in the list will show the data footprint (default app, saves, etc.) but the clean data option is now gone (it was available in the beta versions). You can still uninstall the whole app from there.
Perhaps this is where most of Apple's efforts went. Many are probably put off by the dependence on iTunes. Well, Apple has finally made this a bit easier.
You no longer need a computer to activate your iGadget. The moment you turn on your iPhone/iPad/iPod Touch for the first time, you can do the activation and setup process right on your device (a network connection is required of course). After a few simple steps, quite similar to Android's initiation process, you are good to go.
The whole activation and setip process
You no longer need a computer connection and iTunes to install new firmware updates either. Now you can do it over-the-air. The option is in Settings->General->Software Update. Of course, you can still use iTunes on your Mac/PC to do that if your Wi-Fi connection is too slow.
And thanks to the use of Delta encoding, the updates will now come with a much smaller footprint than before when they carried a whole system image. The new update files carry only the bits that need changing.
The OTA updates
In case you choose to rely on the traditional computer-based iTunes sync, you will be happy to know Apple has now provided an option to sync wirelessly. You just need to have your iGadget and your PC/Mac connected to the same Wi-Fi network. Make sure you've enabled the Wi-Fi sync option in your iTunes client and your iGadget is connected with a cable.
The wireless wync runs automatically as soon as you plug your device to charge and you open the iTunes client on your Wi-Fi connected computer.
Another novelty in the PC/Mac iTunes sync, is that it no longer locks your device during the process. You can continue to use your iPhone/iPad/iPod Touch during the sync process.
You can use your iPhone even when syncing with iTunes (note sync icon at the top)
If you choose to use the iCloud, the only one thing that you may ever need the desktop iTunes is for using the USB mass storage functionality.
Improved accessibility goes beyond the Voice Over, Zooming, UI color switch, etc. The iPhone can now use the LED flash for alerts and you can assign and even create custom vibration alerts to specific events or contacts – much like you would assign a personalized ringtone.
The Assistive Touch is another useful feature. By activating it you get a new on-screen key that stays available throughout the UI, even on the lockscreen and in games. It’s shaped as a homescreen icon and offers a few useful menus.
You can easily move the key in one of the four corners of the screen at any time. Tapping on it reveals four shortcuts – Gestures, Device, Home, Favorites. Every shortcut, except the Home key, opens another submenu.
The Gestures shortuct allows you to simulate two, three, four or five-finger tap. The Device shortcut will allows you to rotate the screen (if available), lock the screen, use the volume controls and even simulate a device shake.
In the Favorites section you have a Pinch gesture shortcut and you can additionally assign six more custom gestures. You just need to perform them once so the iOS can save them.
Creating a new gesture • the gesture menu
The Home virtual key has the same functionality as the hardware Home – you can single/double/triple click it for the relevant commands.
The Assistive Touch is a pure accessibility option that helps you control everything in the iOS with let’s say just one finger.
