I am 12 months into my iPhone 7 and I am in the Apple iUP program. I plan to upgrade to a new phone when they are released. My question is what happens to the 12 months of equity that I have paid into my current phone? Do I get a trade in credit against the monthly fee of my next phone, or do I just lose all that equity like a car lease? I ask because if I were to keep the 7 for another 12 months, I own it outright, but if I give it back now, and I get nothing for it, I question the benefit of staying in the iUP.
