Poor AT&T. This is the second year in a row in which Ma Bell has been tossed under the knife with other carriers and came out dead last in terms of customer satisfaction. The survey, taken by Consumer Reports,  examines voice, data, text messaging services, and customer care; the biggest hit came from... can you guess?... voice. Phone-based customer care also helped the company to achieve its bottom-tier ranking.

Surprisingly, the top position is held by regional-based carrier Consumer Cellular, a provider that, ironically enough, runs off of AT&T's network and focuses on senior citizens. Next in line was U.S. Cellular, followed closely by Credo, a small carrier that utilizes Sprint's network to do its bidding.

As far as the Big Four are concerned, VZW took the top spot; Sprint and T-Mo followed close behind.
