Just wanted to get some feedback. I purchased my iPhone 7 plus a week ago so I can always return/exchange the phone at the Apple Store. Is it worth doing the IUP right now with about 5-6 months away from the speculative release of the new iPhone? I plan on getting the new whenever it comes out in Sep Oct Nov... Should I buy it outright and sell it when the new phone comes out? OR Start the IUP now and pay 12 monthly payments by November (6 months away)?
