This should work with all phones with OBEX (pretty much any phone) and all versions of Ubuntu. I have tried different applications for the task of transferring files from and to my phone. The good thing about this solution, is that the phone will be mounted as a device, meaning it can be incorporated with Nautilus / Rhythmbox / Amarok / F-spot / Picasa / any application you’re using for your music and pictures.

Install needed applications
Yes, this is a copy and paste from my How to use your Nokia to connect to the Internet in Ubuntu. If you’ve already followed the first step in that how to, just install obexfs.

1. Open up a Terminal and copy&paste these 3 commands:
   wget -q http://download.tuxfamily.org/blueman/blueman.gpg -O- | sudo apt-key add -

   sudo wget http://download.tuxfamily.org/blueman/hardy.list -O /etc/apt/sources.list.d/blueman.list

   sudo apt-get update

2. Go to System – Administration – Synaptic …

3. Find “blueman” and “obexfs”, mark them for installation and click Apply

4. When done, all open applications can be closed .

aUPDATE
There seems to be a bug in Ubuntu Hardy’s obexfs. I’m only able to read files. I’m not able to write files to the phone. This should be working in Ubuntu Gutsy though..? The bug in hardy will probably be fixed soon as well.
