Be careful. We 'sold' a mobile on Ebay and we even recieved an email saying that funds had been paid into our Paypal account and we could now post the mobile. It was the first time I had sold anything, but thought it was unusual only because the email addressed me differently to other emails Ebay sent i.e. it used my surname instead of user name. I forwarded the email to ebay and they confirmed that it was spoof mail and I had not received payment.
I could have easily posted it thinking I had been paid and would have just lost the item. There is a big scam going on in Nigeria and they use bully tactics. I remember being very nervous too as they have all your address details etc
IMPORTANT- Don't reply to any emails or click on any links contained in them.

Good luck and don't let it put you off - I have sold lots since, but mobiles just seem to attract this type of scam.
