I've used this feature ( bluetooth tethering ) before on my unit with limited success.. it used to work between my MB300 using "wifi tether for root users" in bluetooth mode but after awhile it caused my phone to reboot and I've since had no luck getting bluetooth tethering to work between my computer / pandora at all otherwise. I've since been using wifi tethering and or USB Host tethering with my Atrix as it "just works" with network manager as long as the Android ROM you're using supports either of the two features
