If you're looking to exchange your old mobile phone for cash DO NOT USE 'SELL OLD PHONE' (www.selloldphone.co.uk). This website is a complete SCAM. I was offered £40 cash cheque in exchange for my old phone, which was a fairly new nokia. I posted the phone to the freepost address given and never received any payment. No-one answers the customer help line and e-mail responses just claim that payment has already been issued. It's impossible to speak to anyone. Just don't do it!
