First off you have to turn on Bluetooth. Second you have to turn on a device to connect to with it and make the connection. So if you do that, you are vulnerable assuming someone just happens to be standing next you you sneering and copying your files like Moms phone number or a recipe for cup cakes. Typicaly the range is 3 feet and it shuts off after inactivity. As cell phones become Dick Tracy mobile data centers, they, like all OS systems will need to be protected. It's like windows 95 connected to the internet back in the day. No firewall, no antivirus no connection to the internet unless activated via a modem. I wonder if those phones affected by Cabir could be patched through the cell net? I would also think those with Palms are safe for now, until an exploit is found of course but then they would have to break my file encryption on the device before getting anything. The latest palms have bluetooth, 802.11 and VPNs built right into the daddy. That makes it a mini-laptop type device in my opinion, the line between phone and computer is disapearing. In fact there are some palm based VOIP apps out there, who needs a cell network anymore?
