I was recently given a Blackberry 7280 that will not work with my ATT/Cingular sim card. I know the phone has been around since before ATT and Cingular merged, but I was wondering if there is anyway I can still use it with my Cingular service without having to shell out a lot of money. Any help on this matter would be much appreciated.
Thank You.
