This guide will perform an untethered jailbreak with iOS 4.3.1 on iPhone 3GS, iPhone 4 GSM, iPod Touch 4G, iPod touch 3G, iPad, and Apple TV 2. Note that iPad 2 and iPhone 4 CDMA are not supported by this version of redsn0w. If you rely on ultrasn0w for an iPhone unlock, do not use this version of redsn0w.
