In this video I discuss the latest redsn0w 0.9.7b1 and 0.9.7b2 untethered jailbreak for the iPhone 4, iPod touch 4G and iPad on iOS 4.2.1. I want to stress that this jailbreak is in beta and as such not everything is working such as Bluetooth and the iPod app. In addition to redsn0w 0.9.7 being Mac only at the moment you also will need access to the iOS 4.2b3 .ipsw for your device.
