The release will include the kernel based GreenPois0n exploit to help with a complete untethered iOS 4.2.1 firmware files.
The release will support all iOS devices other than the iPod Touch 2G. If your iPhone needs a carrier unlock you must use the PwnageTool 4.2 to create the custom firmware files. There is no need to have upgraded baseband and the unlock can be made using your old baseband with the Ultrasn0w version. You will however be needing IPSW files on the iOS 4.2.1 wherever they are needed.
