I'm running Adrynalyne's WM 6.5 ROM v4.0.1-base on the Omnia SCH-i910 (or was that SGH...I can't remember)
I can probably provide a list of programs I installed if needed
MSVC works on my phone over bluetooth, although only if I perform the following steps
- If it isn't working, soft reset the phone
- After a soft reset, activate VC with a hardware button
- Wait for the "ding", say "Help" to make sure it is running
- Sometimes it takes up to 3 presses to get the "ding"
- Enable bluetooth on the phone
- Connect my bluetooth headset
- Test the button on the headset
- Working!
I hope this helps
EDIT: Oh, and my BT headset is a Jabra BT8010
