How do I reset my iPod?

1. Toggle the Hold switch on and off (slide to on and off again)
2. Press and hold the Menu and middle buttons buttons simultaneously until the Apple/iPod logo appears - this may take about 6 to 8 seconds. You may need to repeat this step.

SharePod

"SharePod 3 is a lightweight music management program for your iPod. You can copy music and videos between your iPod and computers usually without having to install anything on the computer."

This is a great application if you're on a computer with iTunes that hasn't been configured to use your iPod. It can be stored and run directly from your iPod which is why you don't need to install it.
