Last month we gave you the rundown* on when we can expect 4th-generation mobile internet speeds from the top four carriers. But we forgot about the little guy(s). MetroPCS is not-so-well known as the fifth-largest mobile provider in the U.S and today its 4G high-speed data network was lit up across L.A. (available only on the Samsung Craft 4G).
