Quick question on transferring upgrade eligibility on AT&T family plan. Another line on my account is eligible for a full upgrade but I am not. I know that in the past you could purchase the phone on the upgrade eligible line, activate it on iTunes (killing the SIM on the phone which has the eligibility), take the SIM out of the new iPhone and put it in the old phone...and then take my SIM and put it in the new iPhone. However, is it possible to order the phone on the upgrade eligible line, receive the iPhone, and put the SIM in from "my" iPhone in without even going through the hassle of activating, killing the old SIM, and swapping out at AT&T? Anyone know if the new wireless activation in iOS 5 might allow for this?
