DevTeam is working hard to release their PwnageTool 2.0. Today it became clear what it will be able to do:
iPhone (1st Gen) with 2.0 - Activated, Unlocked & Jailbroken, (with support for third party applications).
iPod Touch with 2.0 - Activated & Jailbroken, (with support for third party applications).
iPhone (3G) with 2.0 - Activated, Jailbroken (with support for third party applications).
So no unlock for IPhone 3G. But, they promise to create the next version with support of unlock, bootneuter and etc for IPhone 3G. It just will take some time.
