Sprint and C Spire Wireless (formerly Cellular South), which seek to block AT&T's acquisition of T-Mobile. In the filings, it's argued that the two providers represent their own interests, rather than that of the public. AT&T further reveals that C Spire had pursued private negotiations prior to the lawsuit, where the regional provider agreed to support the merger "if AT&T would agree not to engage in facilities-based competition in Mississippi." Ma Bell goes on to state, "This inappropriate proposal confirms that what Cellular South fears is competition, not lack of competition." Given the latest maneuver (which smacks heavily of PR spin), there's no doubt that lawyers for Sprint and C Spire will have a bit of homework for the weekend.
