Big Brother - Mobile phone tracker online
Too late for 1984, but now you can discover anyone's whereabouts, if you know their mobile phone number ! Where's your partner ? Is your colleague really ill in bed ? Simply enter the phone number and get a location on the map..... http://www.sat-gps-locate.com

Funny, very funny John

My work doesn't need it. I am either at my desk on the 8th floor, or downstairs outside on the footpath, "geting some fresh air".
