This one falls in the "it's about time" category: the last of the national US cellular carriers is finally going to offer the iPhone. T-Mobile will officially carry the iPhone starting April 12, with pre-orders beginning April 5.
At the company's Uncarrier event this morning in New York City, it announced that the iPhone 5 will be available for US$99.99 down, and the ability to pay the rest in $20 installments over the next two years -- with no annual contracts.
T-Mobile also will offer the iPhone 4S under the same agreement with $69.99 down/$20 monthly installments over two years and the iPhone 4 for $14.99 down/$15 monthly installments. The iPhone 5 will be available in all markets, but the iPhone 4 and 4S in select ones.
T-Mobile CEO John Legere said that the iPhone 5 offered through T-Mobile will support HSPA+42 in AWS and HSPA+ in MetroPCS in addition to LTE, along with high-definition voice calls.
T-Mobile announced in December that the iPhone would be coming to its network in 2013 and has been encouraging people to bring their iPhones over to its Value Plan since September. As of 2011, more than 1 million iPhones were being used on T-Mobile's network, even though the company did not have any ties to Apple at that time.
