I've got two space gray 6s phones coming, one for me and one for the husband. They're both for Verizon, and when I ordered I put one as a replacement on my line, and the other one is porting his number from Sprint. So when they get here, do I need to make sure I know which one is which? They have separate tracking info (though I don't actually know which is which), so I assume each box will have a packing slip with the order number inside. Or does it not matter, because they're really just two phones and I just need to activate one as me and the other as him?
