Macworld: Secrets: The Linux iPod: “A simple soft reset (press the menu button and the play/pause button) is all it takes to switch back to your regular iPod OS. Want to go back to Linux? Press those buttons again; when you see the Apple logo, press the back button, and Linux takes over.”
Of course when I saw this, I absolutely had to make my 3rd generation iPod run LInux. I remember when this project first started… they have come a loooooong way since then.
