I have an iPhone 6 from launch date last year that I bought on the edge program. I don't know what happens now on Friday. I've paid off 50% of my phone, which I believe was the original agreement I made to be eligible to upgrade by turning in the device. Now that Edge doesn't exist, what contract terms am I bound by? The original: I have paid 50% so I send back the old iPhone 6 and can buy the iPhone 6S on device payment plan tomorrow morning? The device payment plans: I must pay off 100%. And if it's the latter do I make a payment to pay off the device today, then upgrade to the new phone tomorrow and I keep the old iPhone 6 to sell as I see fit to recoup the money I just laid out to pay it off? Very confused.
