The US General Accounting Office on Thursday sent out a report (PDF) warning about mixed results for competition in the cellular industry. It said competition had decayed significantly as moves to consolidate the industry in the hands of just a few carriers, such as Verizon's buyout of Alltel, was making it "more difficult" for smaller carriers to offer a real challenge. About two thirds of cellphone users are AT&T or Verizon customers where Sprint, T-Mobile and smaller networks make up the rest.
