1. Will T-Mobile continue their Jump! upgrade program for the iphone 7?
2. Will I be eligible for the Jump! program if I trade in my iphone 6s (which I bought independent of T-Mobile)?
3. Will I be eligible for the Jump! program if my iphone 6s has a slight screen crack?
Any link with detailed info about Jump! would also be appreciated.
You need to pay the deductible for the screen.
They have jump and you can jump to the next iPhone if you are a jump subscriber.
You will have to start an EIP and add jump. Better to sell your iPhone as you will get more than the trade in value given by any carrier.
