well I've sold loads and had no bother.Eg I'm looked at selling an old Nokia N86 8mp, cash for mobiles offering £26, ebay averaging around £40ish.No brainer if you ask me.It looks like they may have made a mistake on the price they are offering for your HTC, it seems a lot higher than ebay average
What's the best way of ensuring you've wiped everything off your phone now that they store so much shit?
Tell us when they pay up, I've heard a few issues where some companies quote a good price then find excuses on why they shouldn't honour that price once they have received the handset.
