This short guide explains how to use Bluetooth to pair a mobile phone with a Linux desktop computer and use Bitpim to access phone data:
My desktop computer doesn't have built-in Bluetooth support, so I used a cheap USB Bluetooth adapter. I started by installing GNOME's Bluetooth tools. On Ubuntu, that is the gnome-bluetooth package. I also installed the gnome-vfs-obexftp package, which makes it possible to use GNOME's file manager to transfer files between your computer and a Bluetooth-enabled phone that supports the Object Exchange (OBEX) protocol.
