    Unlocking Lumia 900 -- AT&T SIM/Network Lock Code Is Incorrect - FIXED!
    You've probably found your way here because you're trying to use an unlock code that you got from AT&T or an EBay seller, but the phone is refusing to take it, despite your triple-checking of details.

    The workaround is this: Enter the incorrect code until you run out of your ten (10) attempts. Then you'll get the *real* network unlock message, with 32 attempts. Enter the same 8-digit code you've been entering, and voila, you're now free to use this on any network!

    It worked for me
