I know that this subject may of have been posted before, but I will be switching over to at&t with a 1st gen iphone I just got off of craigslist. I heard it is possible to activate the phone with At&t, then you can take off the data plan later. Is this true. I just talked with my local at&t rep, and they said the iphone would not work if the data plan is removed. Is this right? Is there a way to activate the iphone w/o a data plan?
