Ok, so I am switching to AT&T from Verizon to get the iPhone 4 and I am wondering what I need. 1) I am on a family plan with 5 people and would like to take me and someone else off to start the AT&T plan. 2) What info do I need to switch? EX. SSN, Billing info etc 3) What kind of discount do I get with bundled billing? I have ATT Uverse and home phone. Thanks!!
