Well, it did not take long. Sprint revealed today that it has filed a complaint against AT and T proposed the purchase of T-Mobile – AT and T and now is striking back with some less than flattering words. A spokesman for AT and T says Engadget, it shows just what we have said all along – Sprint is more interested in protecting it by promoting competition that benefits consumers. AT and T has also promised a struggle and reiterated that such a merger would ultimately be beneficial for industry and consumers, improving wireless service and resolve concerns of the spectrum.
