> I always take a 2-year contract. About one week before the new iPhone launch (and, conveniently, the end of my contract term), I sell my iPhone. My 6S with 64GB went this weekend for €450, which was the asking price. Next week I won't be able to get that price since there's a new model. I usually sell my iPhones and iPads after the new one has been delivered, preferably on the first weekend of the month. In my experience you won't have to expect a significant decrease in value after release. People know there's a new iPhone - it's not a surprise, even for non-tech audiences, and people will spent accordingly. However the supply will be larger after release, no doubt, but one could argue that this applies to size of target audience as well. People will look for second hand iPhones after release. In any case the resale value of Apple products is nothing short of amazing.
