    Hey guys, I couldn't find info on this so forgive me if there is already a thread.

    I JB and UL my iPhone 3G for T-Mobile USA. I pop my sim card into it and it shows "Locked Sim" where the signal should be. I insert 3 other Tmo sim cards that are on my plan and they work perfectly. My option is to unlock the Sim Card and it asks for a code. I have 10 attempts and haven't tried any yet. I read about a PUK code but not quite sure what that is. I called T-Mobile and the rep I spoke with said they don't support the iPhone so she couldn't help. Also, my sim card works fine with all my Tmo phones.

    Help would be much appreciated. Once again, sorry if there is already a thread.

    You must have put a password on your SIM Card. If you can't remember it, after you get it wrong so many times it will ask you for your PUK code which you can get from Calling T-Mobile.

    And they shouldn't have told youthat they don't support the iPhone, T-Mobile actually has an iPhone tech support division.
