PwnageTool 5.1.1 to create custom pre-jailbroken IPSW firmware has just been released by the iPhone Dev Team. Since past few months, this is the the first time PwnageTool 5.1.1 has received a major compatibility update. But like its previous releases, it applies only to iPhone 4, iPhone 3GS, iPod touch 4G, iPod Touch 3G and first generation iPad only. iPhone 4S, iPad 3/2 are not supported, however.
PwnageTool 5.1.1 main advantage over other jailbreak tool like Absinthe is that it keeps your iPhone’s baseband intact and preserve your ultrasn0w unlock. So, Ultrasn0w iPhone unlockers must use PwnageTool to avoid updating the baseband otherwise you’ll end up in updating to the latest baseband and thereby losing the unlock. PwnageTool will also jailbreak+untether the AppleTV2,1 5.0_2B206f (unless you customize the IPSW further, you’ll have just basic SSH access to the device).
Those who are unaware, PwnageTool 5.1.1 is Mac specific tool that jailbreaks stock IPSW file, adds customizations like boot, adds pre-installed Cydia sources or packages, hacktivates your device, and gives you a custom pre-jailbroken IPSW. You can then restore your iPhone, iPad or iPod touch with this newly created IPSW in iTunes.
