I just picked up my iPhone 3G from my ATT store, the guy made me agree to the contract over the phone using ATT's contract acceptance line. He hooked it up to the computer and registered it then gave it to me and told me he was done. I got home and tried to make a call and was greeted with ATT's contract acceptance line again. I accepted it again and tried making another call. Same thing. I called ATT and they told me to call 1-800-MYIPHONE. Has anyone else had this problem or know how to fix it?
Edit: He used my existing SIM for the whole process.
