AT&T's (T) 4G LTE network is now available in 23 additional markets, including Denver, Columbus, and Portland - as is its custom, the carrier made sure to provide a PR for each one. AT&T, which has said it wants to provide LTE coverage to 150M Americans by year's end, is still well behind Verizon in terms of 4G network size.
