Dante D’Orazio for The Verge:

We reported a few weeks ago that T-Mobile had no intention of letting the iPhone 5’s smaller nano-SIM card interfere with its newly-bolstered plans to woo unlocked iPhone owners over to its network, and now we’ve received confirmation that the carrier’s stores have begun receiving stock of the new SIM cards.

Given the limitations – with the exception of a handful of areas, iPhone 5s don’t support T-Mobile’s high speed network, and you’ll need an unlocked phone (like Verizon’s) for it to work – I don’t expect that many users will go flocking to T-Mobile. But there’s one in every crowd.
