The industry could be on the verge of an all-out price war. Who is responsible for this blessed state of affairs? Credit must go to the United States government. T-Mobile’s resurgence, and the effect it has had on the larger market for cellular service, may hold important lessons for regulators who will soon sit in judgment over the latest enormous broadband proposal, Comcast’s deal to gobble up Time Warner Cable.
