I'm going to buy an iphone for my wife as a present. Walmart has them on sale, i've spoken to people at the store and in person and am getting conflicting info which is why I ask here. My wife already has a phone through AT&T, out of contract and only under her name. Is it possible to buy an iphone and get it setup with her existing number(without her there) if i'm doing it as a surprise for her? Walmart will only activate it in the store. They won't sell me one without them setting it up.
