Cell phones that are merely enabled for talking and SMS are not at risk with viruses. Those that are enabled to handle data or have Bluetooth are susceptible to viruses. Bluetooth technology has few risks so it needs to be manipulated properly. Once virus is installed or received, it will start to look for other Bluetooth devices to infect. Within a 30 feet radius, an enabled Bluetooth mobile device can be infected by another.
