T-Mobile will have 10 LTE devices and its 4G network will be compatible with a future T-Mo-branded iPhone by the end of 2013, chief technology officer Neville Ray said at the carrier’s Challenger Strategy conference call.

“Our 4G network will be compatible with a broader range of devices, including the iPhone” Ray said. Now, this is a clear reference to a 4G iPhone, unless Ray considers the current HSPA+ compliant iPhone as 4G, something Apple has never done. It seems though that T-Mobile's CTO is referring to the roll-out of HSPA+ 3G and 4G services in the 1900MHz range, which the iPhone is compliant with. This is a huge $4 billion investment by the fourth-largest US mobile operator.
The big problem with the iPhone on T-Mobile is the awkward AWS bands that the carrier’s 3G runs on. The iPhone currently doesn’t support them and remains limited to slow EDGE data transfers.
Theoretically, T-Mobile’s LTE network will deliver up to 72Mbps, but we expect the realities to match those of the current LTE networks. That would mean download speeds of between 5Mbpas and 12Mbps.
