The delayed iOS 4.2 firmware has finally been released. The firmware is the first version of iOS 4 to reach the iPad, and makes several feature upgrades, such as support for streaming music, photos and video to an Apple TV via AirPlay, and printing to a handful of HP printers by way of AirPrint. Apple notes that greater printer support and AirPlay-compatible speaker options are expected over the course of the next several months. [updated]
Apple has also announced that Find My iPhone is now a free service, detached from MobileMe. People must however download the Find My iPhone app from the App Store, and have an iPad, iPhone 4 or fourth-generation iPod touch. The company has also opened up direct TV show rentals to iPad owners, giving them a standard 30-day start window and a 48-hour completion time.
Miscellaneous features include expanded enterprise support, and improvements for users with disabilities. Support for 25 more languages has been added including Korean, Portuguese and traditional Chinese. In Safari, users should now be able to find and highlight text.
iOS 4.2.1 is already available as a gold master for developers; it remains to be seen if this is the version of iOS 4.2 that will reach the public.
