I'm on my brother in laws family plan as an additional line cause he gets a sick discount from his job. Anyways, he has an upgrade on his line that he is going to let me use to get the iPhone. I have a My Verizon account. I know that you have to have one in order to per-order the iPhone on the 3rd. My question is, can I pre-order the iPhone or will he have to do it because technically it's his line. Thanks!
