Problem with using mobile as GPRS modem

When a Nokia 5220 XpressMusic is plugged into the USB port of
a PC runing Ubuntu and the PC Suite selected in the phone, a
network connection via GPRS is established automatically.

The configuration date for this connection is given below.

I would like to use the XpressMusic phone with Mandriva 2010.
However, I have not been able to get the facility working
(despite a lot of effort). Could I have some guidance to
plug-in the above information in the configuration files
used by Mandriva.
