Mine are slightly older in both cases it seems:

1.16.666.1
1.59.00

Unfortunately I'll be stuck with them though. After installing more than 50 third party applications over the last few months, I simply cannot accept the notion of wiping everything out and starting over again. It took me ages to get everything installed, patched and configured correctly, and I can't go through all of that again after losing everything in a firmware update. Especially when I don't know for sure whether it will fix anything.

If you do upgrade to 1.59.10a though and it definitely does fix the bluetooth problems, I guess I'd give it some further thought.
