I did an annual upgrade from my iphome 7 Plus to the iPhone X. Pre ordered the Device and received it 11/3/17. Sent in my device. It was accepted. I’ve now had the phone 30 days as of yesterday yet my device agreement still says I have to pay off 100%. Can you only annually upgrade once? This is very disappointing as I was under the impression that I’d be able to upgrade again next year.
