The iPhone Dev Team released the new softwares to unlock, activate and jailbreak the new 2.2 firmware. You can use QuickPwn 2.2 on iPhone EDGE, iPhone 3G and iPod Touch 1G (not 2G).

Note:

They suggest to use QuickPwn for iPhone 3G factory unlocked. You should use PwnageTool 2.2 to jailbreak your iPhone 3G without a factory-unlock, to prevent the baseband update and the future unlocks
