They don’t mix. At least not without a lot of tweaking while in R&D mode. I really meant to mention this in my earlier post about bluetooth PAN on the TMobile Dash, but didn’t. I must be getting old. Regardless, unless you are a linux wiz, or just not overly concerned about hacking the 770, there really isn’t any easy way to get it working with a bluetooth personal area network. If someone figures out an easy way to do it, please let me know.
Here’s a how to from the maemo wiki if you’re feeling up to it. Good luck!
