T-Mobile recently announced that it has finally entered a partnership with Apple, meaning the iPhone should be sold on T-Mobile sometime later this year. While the iPhone isn’t officially sold on T-Mobile quite yet, that hasn’t kept iPhone owners from joining T-Mobile’s ranks. The nation’s fourth largest carrier says that it has been adding 100,000 iPhone activations each month, and T-Mobile now serves 1.9 million iPhones total.
Since you can’t yet buy an iPhone with a contract when you walk in a T-Mobile store, these numbers mean that a signifiant number of customers are bringing over unlocked iPhones from other carriers.
