So I am on Verizon and am going to switch to ATT after I receive the iPhone. Now, tomorrow when I buy one, do I have to sign up to ATT there or anything o can I just buy it and wak out and do everything on iTunes at home? Also, I am pretty sure after I have cancelled my Verizon account, I will be able to switch my old number to the iPhone, correct? And will there be any way to view your plan online and the data, like how many texts/minutes you have left, etc? Thanks a lot
