Got lucky. Cingular has a prmo for Xerox employees to switch from ATT to Cingular. Keep old phone, keep old number, match calling program, new 2 year agreement, new Nokia 6620 for $180.

This phone tends to cost over $200 on ebay.

I do not have my old phone, but if I did, would both old and new work on the same number, even with the old sim in the old phone? the Cingular agent could not, or would not answer, that question.
