MetroPC 4G Coverage extended, but at what cost?

sandytaru writes: I glanced down at my Samsung Galaxy Indulge this morning and noticed my normal 1X data connection had been replaced by 4G. It seems that MetroPCS held true to the promise their salesman made to me back in September and have rolled out their 4G into the extended metro networks (at least in the Atlanta area, so far.) They hoped to have these networks all up and running by the year's end. However, MetroPCS had a disappointing third quarter due to churn, and the question is whether they're going to see a return on investment at all.
