T-Mobile has a strange relationship with Apple. They're the only major U.S. carrier who doesn't officially carry the iPhone, but they're very proud that over one million T-Mobile subscribers are iPhone users. T-Mobile has even went as far as to offer free iPhone micro SIM cards, and are working on building a "iPhone compatible" network. Now they're offering free iPhone support to their subscribers.
