A couple days ago someone explained how when you sign up for the data plan for iphone, they give you a specific plan but you could call them and change it back on the phone. i have the lowest family plan and i dont want to change my plan, incase they cant change it back. is there any way they will let me keep my current plan and just add the 30$ plan? or do i have to do a waltz with the phone jockies at at&t? thanks guys!
