I picked up a small bluetooth dongle at Fry's its by Cables Unlimited. It was 29 USD.
I got it to work with my laptop and my mobile phone (moto V760).
The BTDongle uses the Widcomm Driver (FYI)
So this is what I did for my C1000 (further known as Gimlet).
I went into network and chose BT-PPP. Then for each tab as follows:
I setup my ISPaccount.
For modem I took the BT Device /dev/rfcomm0
Network, added my ISP's DNS servers.
Left proxies alone.
Bluetooth, I checked Bind and then had my mobile phone search for Gimlet. I then got a "Bind with Zaurus" message on my mobile. Once I responded Yes, I was asked for the Binding code and I entered 1234. Once I did that, the Devices and BT address fields were filled in.
I was then able to then connect to the internet - though sometimes I get a message box that reads "TCP error" when in either the Opera or NetFront browsers. Still sorting that out. once I can do that with no errors then it is off to email.
If anyone has ideas about the "TCP" error please let me know.
