When I sync my iPhone 4S to my PC, I'm able to transfer pictures to my PC memory to make more room for my iPhone's memory. Why can't I transfer user made videos to my PC? The user made videos take up more memory than my pictures and so I would like to free up some space for other save data. Is it possible to transfer user made videos to a PC? How?
