When I sync my iPad2 to my Windows 7, I noticed that my iBooks in the iPad2 are not the showing everything in the iTunes Library. I suspect that it also happens with the other contents. I wanted to sync again but iTunes is saying that it will overwrite what's currently on iPad2. What I want to happen is to have all the contents on my iPad2 to show on my PC.
How can I make my iPad2 totally in-sync with my iTunes without buying 3rd party apps?
