Hmm.

Backup.
Apply patch.
Turn on flight mode
Reset

Phone reboots.
Turn on bluetooth.
NO DRIVER message.
Turn off flight mode.

Sync up headset.

Decide to do a reset with flight mode off to see if that was a factor. (I hate a testing methodology where the tester introduces random behavior

Phone comes up.
Bluetooth headset is instantly synched... much much quicker than before.

Will see how it performs after sleep.

Ehud
p.s. for clarification, last time it would not start the bluetooth after the patch at all. I had to hard reset to apply the patch, and then the driver was ok but the tray wasn't. This time it DID start bluetooth and it IS working.
(The phone was restored from a full backup just prior to the first patching.)
