Cell Phone Viruses
The New York Times ran an article about cell phone viruses. Although not the first of its kind, the Velasco worm passes to other phones using radio frequency. Basically, it finds a cell phone using Bluetooth, jumps to the Bluetooth phone and asks the user if they want to install Velasco. If the user says yes, it will install and then try to find another Bluetooth phone. This worm is not malicious, but you can see what the possibilities might be for other viruses or worms.
