Do you have an account set up online for AT&T? If so, you can get a PUK code online to unlock the phone (assuming your phone shows up on your account).
Log into your account and click on PHONE/DEVICE, then click on Unblock SIM Card. From there it gives you a PUK code and instructions on how to unblock the SIM.
