iOS 4.2 Available Today

The anticipated iOS 4.2 release was announced today for iPhone, iPad and iPod Touch.

iPad users can now run their favorite apps and switch between them instantly, while preserving iPad’s legendary 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®, transforming Apple TV into a great accessory for iPad, iPhone and iPod touch. iOS users also will be able to use AirPort Express® and AirPlay to stream wirelessly to any stereo or powered speakers, or directly to AirPlay-enabled speakers coming to market in the months ahead.

AirPrint is a next-generation Wi-Fi print architecture that dramatically 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. iPad, iPhone and iPod touch users can simply tap to print their documents or photos wirelessly to any printer that supports AirPrint.
