I just got BT DUN working with my Blackberry 8830 on Telus Mobility (CDMA). The N800 is running OS2008 2.2007.50-2 and the Blackberry v4.2.2.123.

There were 3 configuration points in the N800 control panel.

* In the Bluetooth applet setup the Blackberry as a trusted device (and did the same on the Blackberry for the N800).

* In Connectivity applet, created a new connection for the Blackberry, with a connection type of GPRS, cellular network of CDMA, and dial-up number of #777. All other options were default.

* The connection didn't become visible until I set the Phone applet to point to the Blackberry.

Yippee!!! Lots of moving parts to get this configured, but it seems to work just fine.

Not to get greedy, but has anyone successfully paired with the GPS in the Blackberry 8830?
