Well, I just did a clean install of Snow Leopard on my Mac and now I want to sync my iPhone with iTunes. However when I try to sync it, it asks me if I want to erase everything on my iPhone and sync it with this library. I do want to do this but what I want to know is, will the sync just effect my music, photos, movies and apps or will it also erase my contacts, text messages, notes, etc? If so, is there anything I can do to preserve those things before I sync my phone. P.S. I made a complete clone of my previous HD on an external, so if there's anything I need to import and/or restore, I should be able to.
