My friend is switching to Verizon as a new customer and pre-ordered the iPhone 5 online today. She is not sure she wants to keep it, so we discussed switching phones. I am a current Verizon customer with an iPhone 4S. Is it possible for us to switch phones, even though we have completely separate accounts? If so, would she have to activate the new phone on her account first, then we each deactivate them on our accounts online at the same time, then reactivate them one at a time? Or could I just activate the new phone on my account and have her activate mine on hers? She was told by an agent at her local Verizon store that she was not allowed to do this for a certain amount of time after purchasing the phone. I appreciate your feedback.
