Hi, I purchased my iPhone in Japan, canceled service (Softbank), now I am back in the US. I am iOS 4.2.1, baseband 03.10.01, model MC605J As of this writing I am confident there is no software unlock for my phone. I want to buy a Gevey Sim, but don't really understand how I could use it. You put the Gevey Sim -- with your sim -- in the phone, then unlock it. Could I still do this with my Softbank sim, given that I am no longer in Japan and no longer have service with them? If not, can anyone think of any way I could use this phone to get service in the US? Thank you very much!
