SIMunlock for iPhone 3G with iPhone OS 3

Less than one week after the availability of iPhone OS 3, which finally brings select/copy/paste among lots of other improvements, there is UltraSn0w, the SIMunlock for iPhone 3G (but not for the new iPhone 3GS, as there is no jailbreak for the iPhone 3GS, yet). Update: just restored my iPhone 3G to iPhone OS 3 via iTunes 8.2, used RedSn0w for the jailbreak and activation and UltraSn0w for the SIMunlock. Works like a charm! BTW: wikisrvd is compatible with iPhone OS 3, so I will have my offline Wikipedia in various languages on my iPhone again soon.
