OK, so i've paired up an A2DP bluetooth headset with my topaz...most things work well, if not great. but there are 2 slight problems: 1) sometimes when i press play on my headset, the screen turns on and doesn't lock. i've already clicked so many things in my pocket by mistake when that happened. and i set the phone to lock when i push the power/stand-by button...but that doesn't work when the bluetooth is connected(works fine when it's not). 2) i usually have my phone on vibrate, but that turns both the ringer and system volume down...so i have to turn off single volume and turn up the system volume...finee..but the settings won't stay. when i take it out of vibrate, both ringer and system volume is at 100%(good) but when i turn on vibrate again, both volumes go back down to 0%(bad) instead of what i wanted, which is: when in vibrate mode, ringer volume can be 0% but system volume has to be at 100% in order to listen to music through my headphones. any help would be very much appreciated!!
