The PAN works fine, but not perfectly. What I found with the N800 and my blackjack is that you can connect them using the same scripts people are using to connect the blackjack to the 770 (there is a thread in this forum about just that)... There are two issues:

1) in the scripts they all suggest you load a module into the kernel as part of the script, this is unnecessary in the N800, I believe it is compiled in.

2) The DUMMY profile doesn't work exactly right, none of the built in apps (opera, IM, etc) will work. I had to install Minimo and GAIM in order to use the connection I could get with BT PAN. I assume this will be fixed eventually, but it hasn't' been yet.
