Most people get a warm and fuzzy feeling when they think about AT&T Wireless. They don't realize that the "real AT&T Wireless" ceased to exist many years ago. On October 26, 2004, AT&T Wireless was acquired by Cingular Wireless, a joint venture of SBC Communications and BellSouth, to form the largest wireless carrier in the United States at that time. This was a strategically brilliant move because Cingular, unlike AT&T had a very poor reputation for coverage and customer care.
On November 16, 2004, all those blue AT&T store signs and globe logos were replaced with Cingular's orange signs and logos, but not for very long. Strangely, a few months later, all of the original AT&T stores that were changed to Cingular branding were once again sporting those AT&T blue globe logos again. In fact, all of the original Cingular stores also became AT&T branded stores. I found that to be one of the smartest things SBC management did.
Coincidently, about the same time, there was another wireless telecom company serving the other side of the country called VoiceStream. They also had a poor reputation for coverage and customer service. Their parent, Deutsch Telecom, decided it was time to change their name too. Say hello T-Mobile!
