I know that you can go on to the AT&T website and to the store, but almost all those phones are the same as what everyone else has. Im looking for phones that are very limited, but that can be used with Cingular. Does anyone know where I can find cell phones that not many people have?

You can buy them on Ebay.

Honestly, your store or agent location really is your best source ...for numerous reasons. Be straight up with them...inquire about the NEWEST device...or ask the salesperson, what phone have you sold the fewest of in this area, etc.
