After Cingular Bought at&t wireless and changed the name to Cingular, they segregated their customers into Cingular Orange (original Cingular) and Cingular Blue (previous at&t customers). They then slowly eliminated Cingular Blue.

But as of June 1st 2007 there is no such thing as Cingular it is now “Wireless from at&t”.

Twenty bucks, says next year it’s just at&t. (not really betting)
