The iPhone Dec Team has just released the demo video of their iPhone 3G unlock and PMP Today said, it does look pretty promising albeit being just a proof of concept since it’s still not yet the final version. In a matter of seconds, the video shows how the once network-locked AT&T iPhone 3G was unlocked to work on T-Mobile. Provided that the final version will run as smoothly and effectively as the one shown off in the video. Well, it’s best time to start jailbreaking your iPhones so that when this iPhone 3G unlock is released, all you’ll have to do is run it.
