UPDATE: Problems in Karmic Koala? Read this: http://cgsbay.com/ipod-iphone-karmic-koala/ and you won’t have them! If you use other distro and iFuse didn’t work for you, try the tutorial, maybe it will work!
I found the program I use in my other computer, mount var/mobile/media from your ipod Touch or Iphone (where the music and photos are) is really easy, you only need to install a program called iFuse. After installing it you can plug in your device and it will appear in your desktop.
If you use Ubuntu, you can follow this steps:
1. Add the package to your sources, symply in the terminal: gksudo /etc/apt/sources.list and add at the end the line you need depending your version of Ubuntu;
deb http://ppa.launchpad.net/jonabeck/ppa/ubuntu karmic main
deb http://ppa.launchpad.net/jonabeck/ppa/ubuntu jaunty main
deb http://ppa.launchpad.net/jonabeck/ppa/ubuntu intrepid main
deb http://ppa.launchpad.net/jonabeck/ppa/ubuntu hardy main
1.2. If you want, in the terminal add the PPA key (it should be optional)
sudo apt-key adv –recv-keys –keyserver keyserver.ubuntu.com e20da6af9caee36095d1282ef104610cf0876ac9
2. Update package list, in terminal: sudo apt-get update
3. Install iFuse, in terminal: sudo apt-get install ifuse
Now you can plug in your ipod Touch or Iphone and it will appear in your desktop.
If you are using other distribution you can check into iFuse webpage to download the program.
