Apple iOS 4.2.1 is now available for download through Apple’s website. This is the public release of the 4.2.1 firmware and supports iPad, iPhone 4, 3GS, 3G and all versions of iPod Touch. The IPSW files of the iOS 4.2.1 are given below.
The new iOS brings tons of new features to the table including Multitasking, GameCentre and Folders for the iPad, AirPrint, AirPlay and some performance improvements for iPhone 3G.
However if you rely on an unlock and wish to keep the jailbreak, you better stay away from this update, atleast for now until new tools are available.
You can now update directly from iTunes 10.1 or download the IPSW file of your device from the links below.
