So I'm wondering if it's possible to exchange my 16gb iPhone 6 in store Friday for a 64gb iPhone 6? I currently have all my lines on edge I was only able to finance $471 so I had to put $180 down to be able to pre order a 16gb iPhone 6. But I am paying off a line on Friday so I'm hoping I'll have more $ to finance on Friday. So do you think verizon would have a problem with me exchanging for a 64gb? Or should I take the chance and cancel my order and try for a 64gb in store Friday?
