wallpapers and ringtones, remove those and see if it takes somehing out, it did for me.
I see about 35 pictures in the wallpaper folder. Aren't they belonging for the iOS? I checked the size of that folder and it's 48mb, i fear removing it as i found it in stash > wallpapers.aUobuW
I don't know what that folder means but i think it belongs to the iOS.
As for ringtones, i do not have one install on the device actually, unless they are hadden somewhere in the system, because i added ringtones times ago, but i've removed them via itunes.
