this ones been going round for a while....basically the winner just gets an email with "information" on how to get a phone for £20.
basically involves signing up 20 or so other people at £20 each which will then cover the cost of your phone.
those 20 people then have to sign up 20 people each to get their phone and so on.

fuckin conners, saw one a while back go for £80, needless to say they werent impressed or so it seemed in the feedback!
