Why does deleted content reappear on my iPhone when I connect via USB?
I recently upgraded from a 3GS to a 4S, and I'm having an issue that's never been a problem before. I notice that music or video that I delete from my iPhone reappears when I connect to iTunes via USB. Nothing is moved over, either: the videos are just listed as if never removed.
I am deleting this videos by swiping across after viewing on phone. They disappear, so I am not overlooking anything on that front. Similarly, I don't sync video or music -- I have manual management checked in iTunes.
Any ideas what might be happening, and how I can fix it?
iPhone 4S, iOS 5.0.1
