Sorry for what seems a stupid question. I ordered 2 iPhones (one for me and one for my wife) via Apple for delivery "by Friday". I had to do a separate order for each of us. However, I don't remember whether I ordered mine, or my wife's first. Will it matter not knowing which phone is which, on on activation via iTunes, or do I assign the number/user of each iPhone then? Or will each phone come with the assigned number/account I am upgrading?
