The obligatory link: Indian chess player caught in Bluetooth ploy
Don't get me wrong here, I'm not trying to belittle the game here at all. Chess is a great game. Still, the only thing surprising about finding out about a player cheating via technology is the fact that it took this long to occur (and be caught).
Now, if he'd just been the witting tool of the ghost of a long-dead master at the game, well... But that's another game entirely.
