tl;dr - If I unbox and use an iPhone 6 Plus and then exchange it for a non-Plus, how much money am I flushing down the drain? How much do I save by never unwrapping the phone? I ordered an iPhone 6 Plus on launch day, 58 minutes after launch. It is 128 GB, Space Gray, and AT&T. I used the Apple Store App on an iPad. My iPhone has not arrived yet. I played with my father's iPhone 6 Plus, and I am afraid it may be too big. It is not too big for my hands (I have large hands), but it is rather large in my pocket. Option A: Open my iPhone when it arrives and play with it thoroughly. Exchange it for an iPhone 6 (non-Plus) if I feel the need. How much money will this cost me? I know the non-Plus is $100 cheaper, but how much of a refund will I get on the unboxed and mildly used 6 Plus? Option B: Do NOT open my iPhone when it arrives. Play with my father's phone a bunch more to see whether I like it. If necessary, return my phone unopened. I am fairly certain I get a 100% refund in that case.
