If you own an Apple iOS device (iPhone, iPod Touch, iPad) then you probably have the 4.3 firmware update by now. It's got some cool improvements, but as usual necessitates a new jailbreak. Enter Sn0wbreeze 2.3b1, the beta version of the jailbreak for the new iOS. It's in beta, so it's not perfectly stable, but this video will show you how to use it. You can see a written version of the guide and the necessary download links here.
