Here is a link to a patched and working Bluetooth driver stack. I am currently using this on my M90 running Vist RTM X86. Follow the driections.http://forum.gsmhosting.com/vbb/show...=291473&page=6
Follow the directions from the website link. Then perform the below 2 steps.
1. After installing to ensure the driver for the Bluetooth 350 was correct, You go to
Control Panel/Bluetooth Devices/Select Hardware
Click the Bluetooth 350(in my case that was teh bluetooth I have)
Manually update the driver, point the installer to C:\Program Files\WIDCOMM\Bluetooth Software\bin
find teh file you need for your card. (for I used the name of the driver it was searchibg for, the name will show up in the file name box below) Rebbot
2. After you reboot enable your bluetooth FN+F2, right click the bluetooth icon in your task bar. Select start using bluetooth. You may have to reboot again and voila a working bluetooth stack.
If you are connecting Bluetooth Headphones and you lose all Sound go to the sound properties and select your speakers as default again. I paired my HT820 headphones and it select those as my default. After switching it back I have had no troubles.
Hope this helps some of you out.
