i asked one of the people who'd bought this information, and it was a site called the mobile matrix. basically you payed them �20 for a cd with stuff you probably wouldn't want on, and they entered you into a list. each phone had a big list and a sub list... the better the phone the longer the sub list. when someone joined they were added to the big list and the sub list, when the sub list got full the next person in the big list got their phone. plus the site didn't update regularly, so you never really knew how many people would be ahead of you. i worked out that for the phone i wanted, about 10,000 people would have to join after me, and that the 10,000th one of them would need about 2 million more - or something like that. So i decided not to pay them �20... suprisingly.
