I have been with T-Mobile up until recently when my family and I switched to AT&T. I am still using my old T-Mobile Blackberry through AT&T service until my new iphone 4s arrives. (It was jail breaked by a kind sir at AT&T) When my new iphone comes in at the AT&T store can I set up the new phone myself, or will I have to have them do it for me? I really want to be able to do it myself because when we went in to initially switch plans the guy was really rough with my family's iphone 3gs's setting them up. I don't want some guy opening my brand new phone up, and tossing it around not giving a care, and spinning it around on the counter and crap. Can anybody give me a link, or a basic idea of how to do this myself please. I know, I'm weird.
