How do I add songs to my iPhone from my Ubuntu 10.4 OS?
I see the iPhone is recognized by Rhythmbox, but I can't do anything with it.
Here is a quick tutorial on how to use any portable device (Cell phones, PDA... ) with Ubuntu.

Syncing with Rhythmbox
After connecting the iPod, open Rhythmbox and click on your iPod name under Devices on the left panel.
You can play music from the iPod and transfer music to it by drag-and-dropping files from the Library onto the iPod icon. Please note: you might need to restart the Rythmbox for it to recognize the album art on the newly uploaded tracks.
You can also install GTKPOD. In some cases it works better, but Rhytmbox has more organizing features.
