Notice: If you have a locked phone from an Apple "supported carried" (eg: ATT) but you wish to jailbreak and unlock the phone for use on a "non-supported" carrier (eg: T-Mobile), you must get your hands on a SIM from the original supported carrier to successfully activate your phone during the iTunes restore. This is a new "feature" Apple has instituted. So find a friend on ATT and ask to borrow their SIM for 30 min. while you jailbreak to 5.1.1 and activate your phone. Then you can use UltrasnOw to unlock and use your "non supported" SIM.
