How to share an internet connection from the PC to a Mobile Device (eg: Nokia Phones). I don't have 3G or Wifi enabled on my old nokia phones, only Bluetooth.
I guess this may work for you
While setting up the new device, check the box Use your mobile phone as a network device. After pairing with mobile phone, make sure to activate automatic connection. To do that, go to the bluetooth menu on your phone -> Paired device -> Scroll to the Ubuntu device -> Option -> Select "Yes" for "Auto-connect".
After that, on Ubuntu, click over the network icon on taskbar -> select "Nokia X2-00 Network". Now it is connected. You are done. Open the browser and try to open any page.
