Notable New Features with iPhone OS 4
- Multitasking.
- Spell check (like on the iPad).
- Bluetooth keyboard support (again, on the iPad).
- User-defined wallpaper (a jailbreak favourite).
- Tap to focus when recording video, just like with photos, and a 5x digital zoom for the camera.
- Playlist creation and nested playlists.
- App folders for sorting apps! You can even put an app folder in the dock.
- Enhanced Mail! You can have a merged inbox view, switch between inboxes quickly, and sync to more than one
- Exchange account. There's also threaded messaging (at last!) and in-app attachment viewing.
- iBooks, just like on iPad, only smaller. You can wirelessly sync books between platforms, a la Kindle.
- Enterprise features, including remote device management and wireless app distribution.
- Game Center. It's like Xbox Live, but for iPhone games. Includes achievements, leaderboards, and match making. It will be available as a "developer preview," and out for consumers later this year.
Compatibility
iOS 4 works with iPhone 4, iPhone 3GS, and iPhone 3G. Not all features are compatible with all devices. For example, multitasking is available only with iPhone 4 and iPhone 3GS.
*Ensure everything is backed up on your iPhone before you upgrade, just in case you loose some data or files.
