Now that you've finished installing the shiny, new iOS 4.2.1 update on your iPad, iPhone, or iPod touch it's time to jailbreak that bad boy -- assuming you're in to that sort of thing. The DevTeam is on the ball, and there's already a compatible redsn0w jailbreak available for you to run on your Windows or Mac system. As always, jailbreak at your own risk -- you could brick your device, and nobody expects the Spanish Inquisition.
If you're looking for the downloads, you'll find them here:
