I was just curious...what exactly does the diagnostics software used by Apple Geniuses tell you about your iPhone other than crashes and when it was last restored (cuz those are the only two I think of off the top of my head)? Like does it tell if you've jailbroken your iPhone? Does it tell if the iPhone was been in water? Does it give info on battery cycles? I tried searching for what it does but couldn't find anything. Anyone know?
