T-Mobiles efforts to transition customers from MetroPCS aging CDMA network to its own GSM and LTE frequencies is going quite swimmingly. The company has been bragging that its well ahead of schedule, and in some markets its already begun repurposing the smaller carriers spectrum to deliver faster Wideband LTE connections. Things are going so well, in fact, that it will begin shutting down the slower MetroPCS network this year, instead of waiting until 2015.
