T-Mobile USA Blames Lack of iPhone for Customer Loss in 4Q 2011
Sequentially, the decline in branded net contract customers was driven primarily by higher branded contract deactivations as a result of the launch of the iPhone 4S by three nationwide competitors in mid-October.Following the collapse of a deal that would have seen T-Mobile USA acquired by AT&T, T-Mobile USA is seeking to reposition itself with a "challenger strategy" and move aggressively to roll out 4G LTE services beginning next year.
