26 March 2013The Verge:
At long last, T-Mobile will carrying the Apple iPhone starting on April 12th. The fourth place carrier announced the news during a press event in New York on Tuesday. T-Mobile, the fourth largest carrier in the US, is the last national carrier to offer the iPhone, following behind AT&T, Verizon Wireless, and Sprint. The iPhone 5 will be compatible with T-Mobile’s new LTE network, which was also officially launched on Tuesday, and will also feature HD voice. The carrier is also selling the iPhone 4S and iPhone 4 in “select markets”; naturally, the older models will only not run on T-Mobile’s LTE network. The iPhone 5, however, will run on LTE, T-Mobile’s “4G” HSPA+ network, and older GSM / EDGE networks — it sounds like T-Mobile’s iPhone 5 either has slightly different radios than the current GSM version to enable full compatibility with its HSPA+ network or had these new bands enabled through a software update.
With T-Mobile now on board, all of the ‘easy’ sales growth sources (that is, an increase in sales by simply expanding the addressable market) for the iPhone in the US have been basically used up.1
1 The added distribution channels of T-Mobile are dwarfed by AT&T and Verizon of course, but still: more distribution will mean more sales.
