Ok, here's the deal: AT&T was the god of communications. Then they were broken up. Then, in the span of a couple years, cingular bought their cell phone service, SBC bought their long distance, and comcast bought their cable. They went from being one of the biggest companies in the world to not existing in a few years by being split into pieces, with the weird result that there are "AT&Ts" out there that provide different services owned by different companies. Let me help. Cingular was owned by SBC. At&T wireless was owned by AT&T. When Cingular merged with AT&T wireless, Cingular became a joint venture between SBC and AT&T. Then SBC bought AT&T, and took the AT&T name. Therefore, in order to put all of their services under the same name, they are renaming Cingular as AT&T wireless.
