yeah. I didnt want to say anything because you said you want iTunes in your system, but if you have linux there are many alternatives to iTunes to manage your music. If you have the KDE desktop then Amarok media player will have full support for iPod and iPhone, if you have the Gnome desktop you can use Rhythmbox or Banshee media players these support iPod too, or you can try GTKpod in as an iPod manager but when I used it did not have play back capabilities.
You can install Amarok in a Gnome, Xfce or LXDE environment just fine too. If you dont know how to install it just let us know what distro you are running and I am sure somebody will point out the right way here in the forums.
