Please help. I ordered an iPhone 6+ on-line, on Apple website, and I would like to know how I could still trade in my old iPhone 5. Or what option do I have. (I know that if I were to go in person, in the store, to purchase the iPhone 6+, I would have the option to bring my iPhone 5 in to trade it. And same at At&t store. Of course I couldn't, because it's in high demand at this time; so I ordered on-line.) So, what can I do? Thanks in advanced.
