For iPhone owners who want the benefit of the 2.1 firmware, but also want to run their jail-broken applications, the iPhone Dev Team has just released PwnageTool and QuickPwn for 2.1 devices. Please note: this does NOT work with the new iPod Touch 2g and is for iPhones or first generation Touch devices only.

The Dev Team managed to work around iTunes 8 without having to patch the program, so pwners can try the new tool without worrying about altering a core OS X program
