So my AT&T account has 4 lines. 3 of which are iPhones and 1 is just a regular phone. Only 2 of the iPhones lines are eligible for upgrade. I went in to AT&T today and asked if I could upgrade the non eligible iPhone line using the dumb phone line and they said I could. I asked them how I would do that if I wanted to preorder and they didn't seem to know so now I come to MacRumors... Sorry if this has been asked before. So how would I go about placing my pre-order using another lines upgrade without having to switch phone numbers?
