My words of advice for all. I already had a 64gb 6+ on JOD. I too was told I could jump to the 6s+ with no extra cost and keep the same monthly payment. I called and ordered at midnight. The rep said I absolutely could not get a 64gb 6s+ unless I paid 99 down. I was upset but then said forget it and decided to get the 128gb if I had to pay a down payment anyway. I then read about everyone getting this free memory upgrade and going from a 16gb to a 128 gb at no charge. I called back at 3am. This rep said there is no such memory upgrade but I could just get a 64gb 6s+ with no extra down payment. I said ok and canceled the previous order and got the 64gb. Today I get an EIP agreement for a normal EIP plan with no JOD they wanted to charge 99 down plus the tax and 24 monthly payments. I called again. This rep said the order was I put completely wrong. He then was able to give me the 128gb 6s+ at no charge. He said there also should be no shipping cost whatsoever on the pre orders. I got the correct EIP 4 minutes later and signed it. Have a new 128gb for free on its way. He also verified I would still be paying the 19 a month after billing credits monthly. I suggest to those out there who have the wrong EIP had to pay for shipping or a down payment for the same memory to call a rep over and over until you get a knowlegible one.
Something tells me you will be in for a surprise.
