Simultaneous Bluetooth connections on 8525

[EnigmaticAnswer]

For the short time that I had the 8525 with the Windows Mobile 5 it came with, I was able to have my bluetooth headset ON (either during a voice call or just on standby) and to use ActiveSync via bluetooth simultaneously. Now, after flashing to the official AT&T Windows Mobile 6 ROM, only one bluetooth device can connect at a time. It's very frustrating to have to
switch one device off to use the other. I know that the phone supports multiple simultaneous bluetooth connections, but it doesn't seem to work on WM6 now. Any ideas?

Same problem here.

I can get my headset and GPS to be recognized simultaneously but as soon as the headset is initiated for a call, in or out, I notice my GPS apps start reporting there is no GPS device.

I've tried many things in an attempt to make it work but nothing helps.
The only thing I have not tried is a hard reset just on the chance it is a piece of loaded software causing the problem.
