iPhone OS hacker, GeoHot, has announced the successful creation of an iPhone unlock for the iPhone OS 3.1.2 baseband. The new app called, Blacksn0w, will allow iPhone users to use their phone on non-Apple sanctioned carriers.

You’ll have to wait a bit though, since the application will not be released by GeoHot until November 4th, 2009.

GeoHot, “To clarify, I have arbitrary code running on the baseband. “
