Yesterday (monday) I accidentally dropped my iphone 4 into a toilet. it was in there for no more than 20 seconds, and immediately shut off once it was removed from the water. I thought this meant it short circuited, but I still went home and stuck it in rise. It's been 24 hrs and I tried to charge the phone. It lit up with the apple sign like it was charging for a few seconds and then went black,and kept switching between the charging screen and the blank screen. Is this a good sign? It is back in the water now.
