An anonymous reader writes "Last week the Department of Justice filed an antitrust complaint to stop the merger between AT&T and T-Mobile USA. Now, AT&T has responded, arguing that the merger would benefit consumers by increasing competition and freeing up spectrum. 'That means increased output, higher quality service, fewer dropped calls,and lower prices to consumers than without the merger,' they say. Meanwhile, House Republicans have sent a letter to FCC Chairman Julius Genachowski and Attorney General Eric Holder asking for an explanation of 'what went into the decision to challenge the merger and whether the agencies considered the impact on jobs and economic growth.' A hearing is scheduled for Sept. 21."
