Apple has announced availability of the iOS 4.2, the latest version of the mobile operating system, to download for the iPad, iPhone and iPod Touch. The iOS 4.2 brings over 100 new features from iOS 4.0, 4.1 and 4.2 to iPad including Multitasking, Folders, Unified Inbox, Game Center, AirPlay and AirPrint. It will now allow iPad users to run their favourite apps and switch between them instantly, while preserving the device's battery life. Users can organize their apps with drag-and-drop simplicity using Folders, and Mail now features a Unified Inbox, fast inbox switching and a threaded message view. Game Center allows iPad, iPhone and iPod touch users to challenge and play friends or be matched automatically with new opponents, showcase their scores and achievements, and discover new games their friends are playing. AirPlay is a new feature for streaming music, video and photos wirelessly from iPad, iPhone and iPod touch to Apple TV. AirPrint is a next-generation Wi-Fi print architecture that simplifies printing by completely eliminating printer drivers. A selection of AirPrint enabled printers including the HP Photosmart, HP LaserJet Pro and HP Officejet will be the first to support printing direct from iOS devices. iOS 4.2 is compatible with iPad, iPhone 3G, iPhone 3GS, iPhone 4, second and third generation iPod touch (late 2009 models with 32GB or 64GB) and new iPod touch.
