As expected, the iPhone Dev Team has just made ​​available yellowsn0w, its unlocking software for the iPhone 3G. 
This is a small program that runs in the background, started during the boot device - ie, there is no GUI for it.
Besides requiring firmware 2.2 (baseband 02.28.00), users need to run QuickPwn to jailbreak the iPhone. The unlock application is available in both Cydia (repository http://apt9.yellowsn0w.com/ ) and in the Installer (repository http://i.yellowsn0w.com/ ).
The yellowsn0w version 0.9 is in beta, which means it has some bugs already recognized by the Dev Team, and others that will only be discovered with this release to the public. If you are not as eager or needed, I recommend waiting at least a second version of the solution. (He left a 0.9.1 update)
