So my problem is very reproducible.

If the phone goes into sleep mode the bluetooth loses connection. Once the VX6600 comes back on, I have to turn off the Bluetooth radio and then turn it back on and then everything works. Obviously this is a problem if you want to answer calls on the headset.

Will the patch discussed above solve my problems? I have read this thread a few times and would appreciate if someone could distill it into a reproducible patch.

Happy New year everyone and thanks for the great research.
