A customer service source inside Cingular sends us some interesting internal documents and says the cellphone company has a new policy that’s got the headset set in a bind. He reports that Cingular will, “no longer discount equipment for customers that are not profitable for us, no mater where they stand contractually. I have received several calls from customers attempting to upgrade, only to have to inform them that although yes, they are out of contract, we will not offer them discounted equipment. “
