My friend has a photo ipod (i think either 20 or 30 gig) that she bought from her brother. It has a bunch of music on it that she does not want to lose. The computer that it was originally sync'D on no longer has all the music on it. we wanted to put new music on it from my computer, but i've heard that if you sync an ipod to a different computer it will delete everything off the ipod that is not on that comptuer, namely everything. Is there a program that will allow me to put new things on the ipod without losing the stuff that is already on there, or to get all the stuff off the ipod onto my computer so i can have both? or something? any ideas?
