I have the old unlimited call for $99 plan on AT&T and just got an iPhone. I called the number from the registration but I don't want to change my plan. What do I need to do to get the phone to work with my old plan?
You can either switch to the new $99/month unlimited plan + $20 for data and 200 sms, or hack your phone with Pwnage and use your existing sim card in the iPhone.
