Hey guys, is it possible to do this? My GF's 3GS is laying around on iOS 5 and it is incredibly slow. I'm thinking since it was the very first iOS 5.0 version, it could be because of that, and am hearing reports that iOS 6 is better performance wise. How would I do this? She is on baseband 06.15.00, and the UNLOCK feature is needed! (Telus service on Rogers iPhone).
