iPhone SIM Unlock Card?

Spotted on swongled.com, this card is thought by some to be an SIM-unlock hardware solution that coots $30. We’re skeptical at best, because this looks like a hoax, but we thought that it might be a good topic for a quick talk at the coffee machine. First, is it possible to do a SIM that would crack the phone’s SIM lock? I don’t think so – what do you think?

Update: This doesn’t “unlock” your phone, but it fools it to believe that any SIM card that you pop-in is an AT&T card, which gets the job done in most cases
