I appreciate the responses guys. Keep them coming. I will be looking into a possible mod with the latest leak but a modified bluetooth stack to resemble/replicate the full functionality of the Cyanogen mod bluetooth on the Droid Incredible.
This potentially could add more functionality to bluetooth:
Connection to more bluetooth keyboards and other devices
wiimote functionality for emulators
Bluetooth SPP and HID profiles are often used in many car types including BMW, Mercedes, Volkswagon, etc. Some people have been posting on the HTC site that they have lots of issues with bluetooth staying paired or even not pairing at all.
I believe we are working with a pre 2.1 Eclair bluetooth stack that HTC never bothered to update. Perhaps this breaks the Sense UI and they don't want to do the coding work for it work. I will continue to look for some answers.
