I am FINALLY updating my IPod Touch from 3.1.3. I have almost 1200 songs on it. I have been leary to upgrade because I don't want to lose my music. Today I had to the heart to ATTEMPT upgrading but then received an error message about backing up my data with error code -5000. I am using ITunes 11. I have already gone to Summary and selected Back Up Now. I went into preferences and confirmed the back up date of today. I even Synced it again just to be on the safe side.
