How does the math work if Apple releases a new phone in Sept. 2018? We will have to make two extra payments to get caught up, so is it still worth it financially rather than buying outright and reselling? (I understand that reselling is more inconvenient)
I am upgrading from (Product)Red iPhone 7 Plus. As long as you managed to pay first 6 month, you can pay the next 6 month worth of payment upfront and go for an upgrade. This is my second upgrade of the year, since I joined iUP last Sept.
