iOS 4 brings over 100 new features, including multitasking, folders, Mail improvements, iBook support and more. The operating system is compatible with iPhone 3G, 3GS, and 4, as well as second- and third-generation iPod touch models. Not all features are compatible with all devices, however, with features such as multitasking, custom wallpaper, and Bluetooth keyboard support requiring a minimum of an iPhone 3GS or third-generation iPod touch.
Users report that the iOS 4 build number (8A293) is the same as that released to developers as the Golden Master Candidate earlier this month.
