I fired up itunes one day, to find out that everything in my iTunes was gone. All my music, playlists, everything. I was kind of upset by this, but not too much, until I went to sync my iPhone. It told me my iPhone was synced with another library. The previous one, on the same computer. No one in my household knows how this happened. Is there any way to use my iPhone with my itunes now without restoring? I have so much stuff on my phone that it is almost out of the question.
