First off, have had a great experience with the SS 4.1 ROM. The switch from OTA 2.1 on my Moto Droid was easy, and the system is very stable. Using Launcher Pro beta makes things very smooth and haven't had ONE fc since rooting (been 4 days now). I'm posting because I've had some issues with BT audio. With 2.1, I could hop in my car and my Kenwood head would automatically pair with the phone, and music/phone calls would be directed to the Kenwood. Since modding, I'd say I have had 50% success getting the phone to connect. I'm not sure if this is a 2.1 vs 2.2 kernel issue or related to the SS 4.1 ROM. Wondered if anyone else has had issues with BT? Perhaps the new official 2.2 release has fixes within it?
