Unfortunately, all of the music on my iPod touch 2G is not backed up in my iTunes library. Long story. I am afraid that by updating my touch, it will have to sync my iPod touch back to my itunes library. Is there a possiblility that updating will cause me to lose my songs because they are not in my library? Please if someone could explain to me what happens as you download (and unfortunately pay for) the 3.0 update.
