I'm not sure what to do exactly. I am doing a "transfer upgrade" and I really don't want to screw this up. If I do it through Apple, I'm not sure I can do the transfer upgrade at the time of the sale. Wouldn't I have to go to the store to get it all sorted out? If I order through Verizon, will I get the iPhone 6 on release day or will they ship on that day? Thanks.
