I configured a USB 2 IRDA cable yesterday to get my mobile phone to work. Unfortunatly the Linux software doesn't support it.
It's not a USB data cable as yours but I needed the same PL 2303 driver to get it.
To build that module you need to select Device Drivers -> USB Support -> USB Serial Converter -> USB Profilic 2303 Single Port Serial Driver.
After that you'll probably need OpenObex and ObexFtp ( http://openobex.sourceforge.net/
) which is the software that let's you transfer files from and to the phone.
Edit: Nokia 6230 is included as a supported device, I guess yours will work too: http://triq.net/obex/devices/nokia
I've just found this prject too, it seems very complete and supports most Nokia phones: http://www.mwiacek.com/gsm/soft/gammu.html
