No really, they do - they said so, look! (extra points if you notice the sarcasm)
These scams really are nothing new, they've been going on for years, though there's hundreds of variations, the plot is always the same - sucker someone to give their details and money (but please Mr 419'er, STOP USING ALL CAPS - IT'S ANNOYING!).
In this case, the phone number they've given is a UK mobile on the Magrathea Telecom network;
Thankfully, Magrathea are fantastic at responding and shutting these down for me (other telco's need to take heed!!!). If you receive one of these, and it begins with an +44 (0044) number, stick it into the following and obtain the company that provides the number, then forward them the e-mail (tell 'em I told you to!);
Hint: I've provided a few you can use over at: http://forum.hosts-file.net/viewtopic.php?f=54&t=340
Damn, they're getting quicker! 10 mins or so after reporting the above to Magrathea, I got a reply (used to take upto a few hours). Thank you Laura!!!

Cheers Laura :)
