TMobile's LTE goes live in Phoenix, Bay area

T-Mobile has started to roll out 4G services in the Phoenix and San Jose ahead of a press gathering today, according to our tipsters. Screen grabs show the service alive and kicking out speeds in the 20-30Mbps range, though we've yet to verify it for ourselves. The company already outed its "UnCarrier" plans on its site earlier featuring non-subsidized smartphones -- including LTE models -- along with unlimited voice, text and basic data plans. We should be able to color in the rest of the details later this morning.
