How to turn my at&t iPhone 4s into prepaid?

I want to use my iPhone 4s on some kind of pre paid network and still use everything like Internet ect. How can I do this?

Call Virgin Moblie Costumer Service. They can connect you iphone I think because they sell iphone on the site.

I believe that the iphone cannont be used on pre paid plans. Call at&t to check.

If its unlocked you can use it on simple mobile $40 unlimited plan.
as far as Virgin mobile, only virgin mobile iphone will work on it, no other iphones unlocked or not will.

If it's att then it will work with with it's gophone plan but don't tell them and activate on phone tell them i am saving up for a phone i will get it next.
