I have a Samsung SGH-A411. It connects and works well with Bluetooth both on my PC and in Hands Free Mode with the Bluetooth Unit installed in my car. At this stage I have done no more than test it statically by both calling and receiving voice messages from my car to a friends mobile and for transferring images from my Samsung mobile camera.to my PC. I still have a lot to learn and am interested in comparing notes with other Bluetooth users!. ANY TAKERS?
