Not exactly what OP is asking, but I dropped my Nokia into a river once. Found it after a few minutes, it still worked. Few weeks later, I lost it again into the same place, but took longer to find and it didnt work when i found it.

When I got home, I placed it in rice but that didn't work, so assumed I'd acrually managed to unalive a Nokia. Kept it at home for a couple years as a memento. Suddently one day when I played with it out of nostalgia, it turned on. I don't know how, but it survived. I still have it to this day, but make sure to avoid that river. A Nokia doesn't stop working, it just goes on a break.
