I will relate this to you all about my Motorola Atrix that was 2 weeks old at the time and you can use the knowledge as you see fit. This actually happened and I still have and use the phone as is.
I dropped it (unawares) into a pond of about 10 inches of water. It was there for a minimum of 25 minutes which was how long we were looking for it. Thank God it landed right side up or else we would never have found it. I asked one of the people helping me to try to call it so we could see if we could hear it ringing. after the 3rd try, i saw it in the water with the display lit up showing me that I had an incoming call. 25 MINUTES IN THE POND at this point. I tore off the cover, stripped it, dried it out and 4 hours later it was and still is fully functional with absolutely no effects from its attempted drowning. This phone is watertight. All i had on it was a screen protector that i had to replace cause water got up underneath it.
