Default Blutooth handsfree problem source still not clear

Hi,

I have radio 1.00.00 version with t he original Asia ROM and something funny has happened:

Since the beginning, I successfully connected to Logitech and Hello II BlueT headsets + a generic car BT handsfree.

I had to perform a hard reset after one of my progs messed the registry and reinstall everything - NOT from a backup but from scratch (less the troublesome prog <g>).

Since then, the BlueT handsfree does not work properly: I hear the ring but there is no volume control from the headset and I hear nothing + mike does not work. The rest of the BT conections work flawlessly, except for some rare disconnects from my BlueT RBT-2001 GPS.

The story in this thread is not encouraging but one thing is clear - the BT problems that I have are with the original radio and EROM and not after an upgrade. I have no clue what all this means except for the fact that tere is something quite problematic w/ the XDA IIi BT connectivity that I didn't have w/ any of my previous PDAs.

I thought to u/g the radio version only but decided to go for a full u/g (less the O2 stuff), hoping that my BT problems will go away.
Please correct me if I'm wrong - should I go ahead with the PUG O2-less upgrade or should I keep the old (but clearly buggy) versions?

Maybe all the problems that we have are connected to specific manufacturing HTC batches? Has anyone researched this? Is there any info correlating between problems and XDA IIi serial numbers?

Best regrads,
Al
