I posted earlier about the problem I was having with my bluetooth headset (blueant Z9) and here is the progress I've made. My original problem was that I could not activate voice command from my headset. I found the following thread very useful
http://forum.xda-developers.com/showthread.php?t=391262 . I followed the registry fixes for my problem but created more problems (sound would not come out of my headset). After flashing my phone again, I reinstalled voice command and it fixed my problem. This is the only ROM I've had this issue with but since I like this ROM so much I was determined to fix it instead of going to another ROM. I notice others having other bluetooth issues. This ROM has had some APPS I haven't had in other ROMS and perhaps one of them is causing these rare issues. Just my 2 cents.
