allow the iPhone to run on its HSPA+ network, its latest move is to add nano-SIM cards for Apple's iPhone 5 to its "catalog" in mid-October.
T-Mobile made the announcement shortly after the iPhone 5 was announced on Wednesday, and it wasn't unexpected. Of the Big Four carriers (Verizon, AT&T, Sprint and T-Mobile, in order of size) T-Mobile is the only one missing the world's single best-selling super phone.
Still, T-Mobile knows it has significant numbers of customers using the iPhone, either in jailbroken and unlocked or just plain unlocked form.
However, the iPhone - and not even the iPhone 5, but all iPhones - doesn't work well on T-Mobile's network. In most locations customers only get 2.5G or EDGE, not even 3G and certainly not the faux 4G HSPA+ that T-Mobile advertises.
However, T-Mobile has iPhone-compatible 4G HSPA+ currently operating in Seattle, Las Vegas, and New York City. In addition, T-Mobile has promised that iPhone-compatible HSPA+ will be available in more markets by the end of this year.
Although T-Mobile is minus the iPhone, several smaller, regional carriers, such as C-Spire, have access to the iPhone, and even pre-paid carriers such as Cricket.
