HOW TO COMPLETE THE UNLOCK PROCESS?
ONCE YOUR ORDER HAS BEEN MARKED AS "SHIPPED" DO:
1. Install latest version of iTunes if you don't have it already (also make sure you have internet connectivity)
2. Connect phone to iTunes with not accepted (not valid) SIM card or valid (AT&T) if your phone requires activation
3. Do a backup
4. Do a restore
5. Phone is now unlocked permanently. (Message should show up on ITUNES usually (if you don't see it, you can always test with a non-supported SIM card).
