My OSX crashed and I installed it completely new (no backup). Now I wanted to import some music into my iPhone and it seems it is not possible. Every time I get the warning that everything get deleted if I synchronize it with iTunes. If I want to manage the music/video manually I also get this message. What can I do? The data on my iPhone should stay. I only want to add something ...
PS: Does it mean that my backup made with iTunes will not work?
