At the risk of getting flammed here, I will comment... all I can say is I am running a STOCK VZW build of 6.5 on my TP2 (no - I can't tell you where I got it, and no I can't give it to you - please don't ask) but the BT problem is FIXED!
My phone now hangs up when I press the connect / disconnect button on my headset!
