Installer Apps Jailbroken iPhone Apps & Jailbroken iPod Touch Apps

Not long ago the Dev Team posted their latest installment of PwnageTool with compatibility for iPhone OS 3.0. There are a few niches though.

Ultrasn0w (the new iPhone 3G unlock) is not out yet. Do not upgrade if you rely on the unlock for service.
iPhone 3G users that don’t need an unlock can upgrade and jailbreak without issue.
iPhone 2G users can upgrade and unlock perfectly.
iPod Touch 1st Gen can be jailbroken on 3.0.
iPod Touch 2nd Gen can NOT be jailbroken on 3.0 yet.

And most of all, PwnageTool 3.0 does NOT work on the iPhone 3GS.

As of right now PwnageTool is only available for the Mac, QuickPwn is not yet updated to support 3.0. But if you get a custom firmware of 3.0, you could use that and upgrade just fine.
