To use UMTS Internet via a bluetooth mobile phone, install the packages [gnome-ppp](apt://gnome-ppp) and [ppp](apt://ppp).

There's a nice manual at [UbuntuUsers](http://wiki.ubuntuusers.de/Bluetooth/Mobile).

1. use `hcitool scan` to find the MAC of your mobile
1. use `sdptool search DUN` to find the dial-up networking details of your mobile, note the line `Channel: 7`
1. edit the file `/etc/bluetooth/rfcomm.conf` and uncomment the section and make the changes according to your details:  
  
        rfcomm0 {
        	# Automatically bind the device at startup
        	bind yes;
        
        	# Bluetooth address of the device
        	device 11:22:33:44:55:66;
        
        	# RFCOMM channel for the connection
        	channel	7;
        
        	# Description of the connection
        	comment "SonyEricsson P1i";
        }
