So I got the 6 the day it came out, and my first mistake was getting it in black(only color available at the time). Over time I have gotten to miss the design and size of the iPhone 5/5S so I have been thinking of downgrading. I have been trying to think of the best way to do this as I do not have an "upgrade" available to downgrade to the iPhone 5S. A few points: -I have a SquareTrade warranty on my 6 which I can get a nearly full refund for -I would like to have insurance on the "new" iPhone 5S, but I don't believe I can go through SquareTrade if I buy a 6 used -I could sell the 6 back to Sprint for $340 or sell it on eBay -I would like to have over 16GB of storage on the "new" iPhone Anyone have any suggestions? Thanks!
