    I'm in Switzerland for a few months so I decided to unlock my AT&T iPhone and get a pay as you go sim card over here so I could continue to use my phone. I went to Orange and got a prepay card but when I put it in my phone I enter in the sim unlock code and it says "PIN entry succeeded" but it doesn't connect to the Orange network, it just says no service. This happens every time I restart my phone and try to unlock the sim card. Anyone have any advice on how to get this working?

    Are you sure your phone is unlocked? When I jailbroke my phone and unlocked it, I wasn't asked for a SIM unlock code. If possible, you should disable that, because it has nothing to do with whether your phone can accept other SIMs.
    If necessary, reinstall ultrasnow.
