T-Mobile USA nano-SIM poses for the camera, may arrive in October (update: official)

T-Mobile's American branch would really like to scoop up a few iPhone owners, and we're getting a better sense of just how far it's willing to go to lure refuseniks who'd otherwise go to AT&T. A product matrix leaked to TmoNews both shows the US carrier's specially branded nano-SIM cards and suggests they'll be available in October. And while there wasn't really any doubt, the cards should be in stores just for unlocked iPhone 5 models -- "no T-Mobile devices require this SIM card," the company tells its staff. The wait could be a pain, but the sighting at least provides some comfort to those who would only let their iPhone 5 run on Magenta's network.

Update: Talk about under-the-radar confirmation: T-Mobile has mentioned in conversation that it hopes to carry nano-SIMs in mid-October.
