T-Mobile has done it again: J.D. Power and Associates recently ranked the carrier as No. 1, for the fifth time in a row, for providing the highest level of overall customer satisfaction. J.D. Power's 2007 Wireless Regional Customer Satisfaction Index found that T-Mobile ranks ahead of Cingular/AT&T, Alltel, U.S. Cellular, Verizon Wireless and Sprint Nextel in three of six regions surveyed: the Northeast, the West and the Southwest. In the Mid-Atlantic area, T-Mobile tied with Verizon, and in the Southeast, the carrier tied with Alltel. There was a four-way tie in the North Central region between T-Mobile, Cingular/AT&T, Alltel, U.S. Cellular and Verizon. Poor Alaska and Hawaii didn't even get to participate.
