Connecting to internet using phone as modem through bluetooth

I’m using nokia c2 phone and i tried to connect to internet through bluetooth in opensuse 12.1
after entering all the details in bluedevil’s mobile broadband connection, i clicked on finish.
i had ticked connect automatically, but nothing happened.
when i opened network connections, mobile broadband tab was disabled or not clickable (greyed out).
so i tried the same thing again and when i rebooted my system after a while,
when the desktop loaded, there were around 4 or 5 bug report windows all pointing to bluedevil…

>what am i doin wrong?
>is there any way i can use Konsole to create the mobile broadband connection?
>why is the Mobile broadband tab in network connection grayed out?

can somebody help me pls
