I decided to wait a few days to make sure and I can confirm that the new ROM update does fix the "Beep of Death" issue that was on this unit originally.;
One other thing that is better... Bluetooth support is working like it should. I no longer have problems with pairing my headset, nor is there any problem with the phone waking up the headset when they have been apart for a while.
All in all, this is awesome and I would recommend that all users of a PPC-6601 upgrade to this new ROM revision.
