I just got back from the AT&T store at Rockefeller Center in NYC. They got a grand total of THREE iPads, all 32GB. I bought 2, and finally made the switch from my grandfathered unlimited plan to a 6GB Mobile Share. It'll only cost $20 more a month but I've got the 2 iPads on it now, we rarely go over 4GB combined on our phones, and the iPads rarely leave our home with WiFi.
I put them on the Next plan, and if you're already an AT&T customer they do not run a credit check (in case anyone is curious).
