Yes, that was it. I'm now happily connected with pppd on channel *5*. I 
thought those would be fixed in stone for the phone model.

John, as to how to pair the phone and the PC.

First, under "Setting -> Setup/Others" choose to update your software. 
I'm on v18. Apparently v17 and v18 have updates for BT.

Then on Settings -> Bluetooth turn visibility on and also change your BT 
name if you want.

Then under Bluetooth from the *Main* menu, enable BT and do "Add New." 
and also click "enable" for the computer, which will enable DUN. I think 
you can either choose to search and pair or just wait for pairing. Then 
some trial and error, I can't give you an exact formula, but you will 
have to type in the same pin on the phone and the PC (I use KDE's 
bluetooth pin helper and KDE's BT browsing). The phone will tell you if 
the pairing is sucessful.

Also, according to 
http://www.sprintusers.com/forum/archive/index.php/t-57061.html you may 
have to do several iterations of enabling and disabling a device to get 
the pairing to work.

The nice thing is once you have it paired, you can just leave it paired.

Good luck, e-mail me privately if you want more help.

Eric
