A cross-platform jailbreaking, unlocking, and customizing tool for iPhones and iPod touches. Customizations include boot logos, recovery logos, and “verbose” boot. It’s a standalone program that doesn’t use iTunes (no custom IPSWs are involved).

We’ve been offering redsn0w in various incarnations over the years (including poorlad’s Windows version of QuickPwn). The most recent release before this one was redsn0w 0.8, which targeted Apple firmware 3.0/3.0.1.
Update July 5th, 2009: GeoHot now also provides a Mac OS X version of the jailbreak tool. Windows and Mac versions ready for download at purplera1n.com…
That’s it with the 3.0 firmware and the iPhone jailbreaks. Apple has been beaten again. This time by GeoHot. Although the iPhone Dev Team seems to have their programs already prepared they preferred to wait with the release of an updated PwnageTool. GeoHot did not wanna wait and decided to release a Windows based jailbreak tool for the iPhone 3Gs called PurpleRa1n.
All three iPhone generations can now be activated, jailbroken and unlocked with the current firmware 3.0. Currently for the iPhone 3Gs there is only a Windows version available that is under strong beta testing. Anyway you can give it a try. The security whole that gets exploited in the iPhone 3Gs is well known as the 24k bug that has been found in january in the iPod Touch 2nd generations.
