Before the official release yesterday, website's noted a jailbreak guide for iOS 4.2.1, long before the update made its way to anyone outside of the Apple developer community.

While we don't condone jailbreaking, if you do decide to go this route, watch out: the latest version of Cydia doesn’t work with the iOS 4.2.1 jailbreak and will crash your device. However, a fix is in the works, so stay tuned.
