T-Mobile USA Customers Being Shipped Micro SIMs, Possibly For Future iPhone?

We’ve had plenty of T-Mobile iPhone rumors going around recently, especially since T-Mobile decided to begin offering iPhone cables. Now some T-Mobile USA customers are noticing that they’ve been shipped Micro SIMs instead of the typical Mini SIMs, with one such card pictured above. The prominent devices that use the Micro SIM at the moment are Apple’s iPad and iPhone 4, though whispers are going around that the Micro SIMs are actually for a T-Mobile variant of the Galaxy Tab. There isn’t any official word on what device the Micro SIMs will be used for at this point in time, but you have to admit that it adds an interesting twist to the whole T-Mobile iPhone deal.
