I have some 16gb iPhone 6 T-Mobile phones but really don't think I can do 16gb. The iPhone 6 seems pretty easy to get though, so I don't even know if there's any value in trying to flip them? Paid $702 for them... I'm assuming $800 would be the MAX I'd get on Craigslist. I know on eBay, they're going for a little more but after the fees and shipping and hassle, I don't think eBay is worth it compared to cash from Craigslist.
