If I erase and sync, will all of my photos be erased?
I recently got a new iphone and my mom accidently synced it with her computer, so now I can't sync it with mine without getting the "This iphone is synced with another computer, would you like to erase and sync with this computer" message. I've already transfered all my pictures onto the iphone and I really don't want them to be erased, same with contacts. If I erase and sync, will it only erase and syn the music? If there is a chance that my pictures and contacts will be erased, is there a way to prevent losing them without saving all of my photos to my computer?
iPhone 5c, iOS 7
