Just for reference – found this site, iPhone.Unlock.no, to be by FAR the best site for unlocking your iPhone. It addresses most situations, 1.0.2 and 1.1.1 unlocking, unbricking, jailbreaking, activating and all.
Note: 1.1.2 out of the box(OTB) iPhones have not been unlocked via software as of yet. This has only been achieved by using TurboSIM – a very cool product – a SIM card and APIs to develop SIM Toolkit applications + 802.15.4 2.4GHz radio for mobile phones AND ZigBee optional! The “hackers” used it to unlock the iPhone’s GSM features.
