Finally at long last and a week following the official iPhone 3.0 release by Apple, the iPhone Dev Team has released #UltraSn0w. UltraSn0w allows iPhone 3G, 2G and 1.0 to unlock their iPhones to use on any carrier. Using #redsn0w, you can jailbreak the iPhone 3.0 OS and then unlock with #ultrasn0w after that.

The instructions and download links are can be found at http://blog.iphone-dev.org/post/128573459/ultras-now

Note: If you’ve previously jailbroken your phone, you should execute a “Restore” from iTunes after upgrading to 3.0. There have been problems with poor battery life and call reception on 2G and 3G phones.
