My wife and I both plan on switching from ATT to VZW, we tried pre-ordering 2 iPhone 5's at the same time, and got that "only 1 carrier activated phone per order" error. So I ordered mine first, and my wife's second in a totally separate order. Once we have the phones in hand, will it be relatively easy to set one phone up as the primary and activate the second phone as an added line on VZW? All this while porting our numbers over from ATT to VZW? Figure 1 or 2 of you must know from experience. Appreciate it!
