That didn't take long. Give the iPhone Dev team a couple of days and they can seemingly do anything, including pump out a jailbreak for the just released iOS 6.
This is a developer-only release, meaning it's not meant for the faint of heart, and should be approached with extreme caution. It also doesn't work on the iPhone 4S yet, but if you fancy tinkering; don't mind losing your unlockable baseband, and have apps you want to test, you can try it out now. One caveat though, Cydia isn't quite ready yet, so the only way you can access the phone is over SSH or afc2 -- if you don't know what they are, I'd stay well clear of this one. [iPhone Dev Team]
