Ehud,

Thanks for your info. You are not going crazy. I've done what I think is the same thing twice and got different behavior.

If you ever get the memory error. Try waiting a few seconds and try turn on again. After a boot I think some things are still going in the background. Try this a few times. Many times with 3500 I say start BT, it gets error, start again gets error, start again and it says ok. It always starts smooth if already on at boot.

Also when you say "new DLL".I assume you mean audiogw.zip I uploaded.

I have not figured out these backup programs quite yet. That's why I said only sure fire way is hard reset and apply patch and rebuild. But there most certainly are shortcuts if you know what you are doing. Amazingly I avoided a hard reset after about 6hr's of testing different combo's to find audiogw.dll issue.

Build 3100 is definitely the most stable. Still not sure if 3500 really is much better or not and worth putting up with it's quarks. 3500 is much better behaved with audiogw.dll from 3100.

If I see any missbehavior I'll bttrayce like you did from 3100.

Oh and I think it's normal that the DUN will shutdown when call comes in (on PPC-6001 not sure about EVDO). And on PPC-6601 anyway you don't need to run wmodem for bluetooth DUN connection.
