So I'm going to sell my iPhone 5S 16GB, it's only 4 months old as I had to get a new replacement phone in September from Apple as the update wrecked my old one. No marks on it, put a protective cover on it as soon as I took it out of the box so it is in excellent condition. I'm buying out of my contract which is costing £400 probably moving to Android. How much will I get for it? They are £449 brand new Sim free. Also what do you think of the HTC One M8?
