My wife has a 5s and wants a 6+. She's not eligible for an upgrade till next yr, but my son is and she'll take his (he's 17). We can do the upgrade transfer through ATT (online and store) and order the iPhone, but delivery isn't until mid to late Nov. Since she wants it ASAP can we order it through Apple under my son's name to get subsidized pricing and when we get the phone call ATT to do the upgrade eligibility transfer? I've heard conflicting info, so wanted to see if anyone here has done this. Thx!
