Just got my 680 and as it being my first smart phone.. I'm pretty pleased.. Except for one small issue.. All my previous phones, whenever the Bluetooth Headset was active.. The phone would automatically go into Silent Mode and disable the Audible Ring tones.. The 680 doesnt, at least I can't find the settings.. Anyone know how to do it? If at all? I would like my 680 to vibrate when my Bluetooth is turned on and paired.. Its annoying to constantly flip the Sound switch..
