I wanted to post an update to this thread to find out if my current experiences have been noticed by others.

Since doing a clean and fresh Flash upgrade of the OS and eMMC to PR 1.2, a lot of my BT issues are resolved. My Jawbone Prime that was unusable before is perfect and crystal clear. My Blueant Q1 that had unresponsiveness problems where the earpiece would "freeze" up and become not usable till it was restarted/power cycled. also seems to work better.

Anybody else noted some of their BT issues were resolved?
