If you are the original jump customer you dnt have to pay the any balance. If you signed up fr jump in the last one year then you may need to satisfy to pay 50% ( not sure exactly) of you phone retail price to be eligible to upgrade. I am the original jump customer and still have a balance of $434 on my iphone 6 plus. I just upgraded using jump to black 128 gb. Jump porgram paid off the balance $434 on the current phone and i was able to pre order 7 plus black 128gb . I just had to put downpayment of 149 plus tax 54 though. Estimated shipping day sep 27th
