In this State of Jailbreak video I discuss the newly released ultrasn0w 1.2 unlock for the iPhone 3G and iPhone 3GS on baseband 05.14 and 05.15 and iOS 4.2.1. In conjunction with PwnageTool 4.1.3 Unlock Edition for Mac and redsn0w for Windows you can upgrade your baseband to 06.15 from the iPad 3G.
