Apple launched the iOS 6 Beta 3 just a couple of days back, and the redsn0w team has given out a jailbreak for the latest version of iOS 6 already. The only downside is that this is a tethered jailbreak, which means you will have to make sure your phone is connected to the computer whenever you need to reboot it.
