Yes, there is a way to tell if it is refurb. I am drawing a blank on the exact details of how at the moment. Its one of the numbers on the sticker under the battery, cant remember which one. I found out when exchanging a 7290. The Cingular return agent stated that the refurb units start with a zero. If I had a Cingular unit in from of me I would know it if I saw it. Maybe one of the Cingular employees that post here can confim.
