See the upper left hand corner of this photo, folks? It says T-Mobile. Cool, no? I like T-Mobile more than I like AT&T. That’s just me, though.

Gizmodo has video of iPhoneSIMFree’s software at work. It looks real easy, too. Like a baby could do it if you pushed the aforementioned baby’s little hand down on a couple of buttons every now and again. The whole process takes less than five minutes.

The visual voicemail does NOT work, as it’s not supported by T-Mobile. If that doesn’t bother you, though, this might be your best option at ditching AT&T should you desire to break away. Cool stuff.

The iPhoneSIMFree will be made available to resellers very soon, so be on the lookout for your local non-AT&T phone peddlers to perhaps start stocking iPhones.
