My girlfriend is eligible to upgrade via 2 year contract to a new iPhone on Verizon. She had planned to just get the iPhone 5s (she has my old 4s). I offered to give her my 5s and pay the upgrade cost for a 6 and just activate it on my number when it arrives. Is this possible? Anything I need to look out for if purchasing it this way? Would activating it on my number register it to me with Apple? Would I be able to purchase Applecare for it in my name? I guess this would be like if she bought one and gifted it to me, but I don't know if this would work.
