iPhone X: how to sell your old device in preparation for Apple's new release

Apple's hotly anticipated smartphone is coming in November and selling your existing iPhone is one way of paying for it. But timing is everything

The iPhone X is coming soon, and if you want to be able to afford it, you have three options: travel back in time and buy a shedload of bitcoin; sell a kidney; or sell your existing phone and hope you get a good price.

That third option is probably the best. But if you haven't sold a phone, it can be daunting: may people like to hang on to their old model, "just in case", and even if it just sits gathering dust in a drawer somewhere, that's less stressful than having to deal with exchanging cash on the internet.
