It took a little longer than what many expected, however, there is now a verified SIM unlock application for the iPhone.

Ryan Block from Engadget has posted a video verifying that the iPhone SIM unlock software from does indeed completely unlock the iPhone from AT&T.

We can confirm with 100% certainty that the software solution completely SIM unlocks the iPhone, is restore-resistant, and should make the iPhone fully functional for users outside of the US.

Engadget could not confirm that the iPhone SIM unlock software is update resistant, however, they do say if you have to restore your iPhone (they restored to v1.0.2) after the unlocking process, all you have to do is “fake activate” your device, pop out the AT&T SIM, put in the non-AT&T SIM of your choice, and reactivate.

We don’t think Apple will see any decline in sales. As a matter of fact, just the opposite may happen. There are still a lot of fanboys out there that want an iPhone but simply cannot use AT&T. The would, however, be willing to buy the device direct from an Apple store and unlock it. isn’t yet selling their iPhone SIM unlock software to individuals but they are accepting inquiries for bulk purchases of 500 licenses and above. Per unit licenses will be available next week.
