thanks huiqing for the info....thats mean i need to copy out my music/photo/video out first and place in the folder to be sync back to my iphone? if gone meaning all the photos under camera roll totally deleted? 
I'm not sure about photos in camera roll; but you better make a backup yourself, as they can be easily copied out from the phone.And, it will be very difficult to copy music/photo/video out from iPhone, as they are all separated and stored in random folder with random names.
You can try use iFunBox, there's a function to search for music files in your iPhone.
Photos are all stored in \var\mobile\Media\Photos\Thumbs\
Videos are all stored in \var\mobile\Media\Photos\Videos\
