I came back to offer VoIP.. well done that man! As for discussing how to tap GSM on an open forum. Its right that we discuss it here - we can show our own community how vulnerable we are. Theres a certain nievity in the way we conduct our lives in the electronic age, but nothing has changed. Since Phidippides launched high speed communication we've always tried to intercept the message. Back in time, we would mug the runner, since AGB we put a man in the exchange and undoubtably thats whats happening now - if the police out there are subject to corruption, so are all the other walks of life.
