Today I realized that I hadn't backed up my 4S in a while so I opened up iTunes. When I tried backing it up it gave me an error, and I did some research and found that people solved it by deleting their old backup, so that's what I did. After that, when I tried backing up again I got an error "The iPhone 'iPhone' could not be synced because the sync session failed to start." I decided to upgrade to the latest version of iTunes to see if that would help, since I wanted to upgrade it anyways. Now when I plug in my phone, iTunes says that it can't read the contents of my phone and that I have to restore it. Long story short, I now have no backup and am faced with wiping out the music and apps I bought since I last synced with iTunes. And I don't have iCloud, by the way. Any help?
