What is the track record of trying to sell iPhones for the full price (the extra 150 that is subsidized)? Like how many people are able to sell let's say a 4S, normally 350 without a contract, for 350. Do people still buy at that price? I planned on selling my 4S, but my brother might steal my upgrade so I wouldn't get the 150$ discount. Do you think I would (easily) be able to sell my 32GB 4S for $350 on Amazon, or would I have to sell it for $200, at which I would just sell it to Gazelle?
