Seems the iPhone hackers are quick of the mark these days, as cnet is reporting that only just days after Apple released an update to iPhone OS 3 beta, hackers have now jailbroken the release.

Yes iPhoners a new version of QuickPWN, but for Windows only, is now available and apparently works with all versions of the Apple iPhone and Apple iPod Touch.

Sources who have tried the new jailbreak are reporting no trouble with the new hack, however, the iPhone Dev Team say that using the new jailbreak will kill yelowsn0w forever, and of course downloading and using QuickPWN is at the iPhoners own risk.
