"Bitpool"=dword:00000080
"MaxSupportedBitPool"=dword:00000080
"UseJointStereo"=dword:00000002
"SampleRate"=dword:0000BB80

One problem I have noticed on my Sprint Touch when using the above A2DP settings is that I lost the ability for simultaneous bluetooth connections. With the above settings, I can be listening to BT stereo flawlessly but when I connect my outboard BT GPS receiver to the Touch, I lose the BT stereo sound completely. When I turn off the GPS receiver, the BT stereo comes back on. I believe the above settings maybe too bandwidth-intensive to allow for simultaneous bluetooth connections or it could be the limitation of my BT stereo headphones (Jabra BT320s). Others have recommended setting Bitpool and MaxSupportedBitPool both to 48 but the problem of GPS and AD2P working together still remained with my hardware. I finally compromised and set Bitpool and MaxSupportedBitPool of 40 and now I can use my GPS and Bluetooth AD2P concurrently.

For those who have done this tweak and have a GPS receiver, you may want to test to see if you still have simultaneous BT connections working. If you don't have GPS, try listening to your BT Stereo headphones and transfer files at the same time using Bluetooth Explorer.

Hope this helps.
