A doubly bad day for AT&T: Second iPhone unlock publicized

As Erica announced earlier today, our colleagues at Engadget confirmed a software-only unlock for the iPhone that's got their unit happily working on the T-Mobile network. Fine and dandy, but here's where it gets confusing. The AP/CNN has reported that a New Jersey teenager named George Hotz (with the help of some friends) has also unlocked the iPhone for use with T-Mobile; this unlock is described in the story as taking "about two hours" and involved expertise with "both soldering and software," so clearly it's not the same process as the software-only unlock from iPhoneSIMfree.com that Engadget has verified. Commenters inform me this is the same George who appeared in a YouTube video a couple of days ago with a claimed unlock hack.

Aside from the TurboSIM process, these unlocks are the first widely-publicized and (presumably) stable methods of unlocking the phone. What are the odds of two completely different methods of unlocking the iPhone hitting the newswires on the same day (even if the George Hotz unlock was announced earlier in the week)? I'm no statistician, but I'm picking up a lottery ticket just in case.

Thanks to Lisa, Rae and Rikin for sending this in.
