I recently bought a 30GB iPod, and I gave my mom my old iPod mini. I want to delete all of the songs on the iPod mini, so I can put the music she wants on it.. is there any way I can delete all of the music off of that iPod, yet still have all the music in my iTunes, because I still want that music on my new iPod. I have no clue how to go about doing this.. help??
