It's an unlocked phone presumably meaning that you COULD get one for $600, but it would be subsidized and locked into a carrier for 2 years. This phone wouldn't have that problem and was bought unsubsidized. My brother recently upgraded to a 128GB 6 and retail on that is something like $970 so it stands to reason that retail for a substantially bigger phone (and the one that's harder to find) would be more expensive. Either way he's dreaming if he thinks someone is going to buy an unlocked iPhone from him for above retail. I've got a 64GB Plus ordered and estimates are that they'll be in by the end of the month. After the trade in deal it was about $200 after re upping with Verizon. I guess he's hoping that people who don't have upgrades will just bend over in front of him.
