Hi, my iphone was working perfectly last night, then this morning when i went to import some songs into itunes from islsk the program crashed to springboard then when i went to the ipod all my music was gone! i connected to the computer and itunes gives me a message saying "Itunes cannot read contents of Iphone, go to summary tab and restore"

I ssh'd into the phone and was able to locate the music file and all the songs were in there so i tried to delete them to see if that would help but it did nothing. Anyone know if there is a way to fix this or am i going to have to restore?
