wow alcolepone, I'm sorry to hear Cingular screwed up your new unit. I just got mine today and took it to the local Cingular store. The tech told me that my 7290 which I had for just under 2 weeks had the new 64k card so he simply took the new SIM out of the 8700 and popped in the SIM in my 7290. Everything worked just fine. He told me just to hold on to the new one.
