Bundyo, thanks for the info. Until recently I have never used a bt device or looked up the tech/capabilities. Does the fact that Nokia's own device will pair with the 770 mean it works as intended. Will *any* equivalent bt device work? What exactly do you mean by "sound is not routed through the headset"?

PS: I am especially keen to hear from anyone who has successfully used any *ultra cheap* bt devices with any combo of tablet/os.
