Last Thursday, we ran a piece about the new generation of iPhone hardware not supporting T-Mobile’s emerging 600 MHz network, known as Band 71.

There was a lot of discussion about this, both on whether the new network will be out soon enough to even matter, and whether support for this future network should impact someone’s choice of T-Mobile as a network.

Peter Cohen sheds light on the coverage issue here, well worth reading if you are a T-Mobile customer or considering a carrier switch.
