Let's say I buy an iphone 32 gig (as an upgrade on my account with new 2 yr contract) and my gf upgrades her phone to a 16 gig (also as an upgradge on her own account). When they arrive in the mail and we decide we want to switch phones before activating them, can we? Can we just enter in the other phone's IMEI number? Or is the order number and activation number associated with the specific phone we ordered.
If not, can two iphone users just switch phones? Would there just be an activation fee?
