Default New AT&T Blackberry 7290 and My Existing Cingular SIM...

Please Login to Remove!

Hi. Hoping someone can help here. I just got a new Blackberry 7290, AT&T branded, but when I put in my existing Cingular SIM card in there, I get a data connection refused error although the phone works fine. Calling Cingular/AT&T for help, they tell me that the AT&T and Cingular data networks are not compatible and that there's no way for me to use my Cingular SIM on my AT&T Blackberry. Is this true? I'm thinking there's some setup things that's required for my existing Cingular account for me to access the Blackberry network, no? Please help. Thank you.
