OT-- Interesting test I just did. I turned on a "Bluetooth" wireless earpiece to my Motorola cell phone and then checked both the phone and the Bluetooth for RF, ELF radiation, etc. with a device I bought made by "CellSensor". The phone itself up near where your ear goes, when in use, made the tester sound like a very busy geiger counter, while the Bluetooth, when receiving, showed virtually no signal on the tester. Going to buy a bluetooth and compatable cell phone for all my kids and make them swear a blood oath they will use them--g
The only other really safe way to use these cell phones is to use the speaker that is built into some of them IMHO.
