The iPhone Dev Team has released PwnageTool 4.2, which is now untethered thanks to the help of the Chronic Dev Team. With their permission, the Dev Team has included this exploit in PwnageTool 4.2.

What is the difference between PwnageTool and GreenPois0n? By using PwntageTool, unlockers can safely restore to a custom 4.2.1 pre-jailbroken IPSW firmware and still retain the current baseband and unlock.

By the sounds of things, pod2g and the chronic team will probably add this same support that PwnageTool includes.

Supported Devices include: (Mac OS X Only)
