On the most recent software upgrade I lost all the music that was on my 2G Itouch. For most people this is not a problem because they just add the music from their Itunes library back on to the Itouch. However, I loaded my music from 2 different computers and only updated the music information on the Itouch, not either of the Itunes libraries. This means that the tagging is perfect on the Itouch but not on my Itunes. Is there any way to just backup my Itouch?
