A friend of mine passed along a great tip that just might help you save your cell phone if you happen to submerge it in water:

“Hey All,

Last week my husband, Dennis, was taking pictures of a house for our new listing. He kept moving backwards to get the best shot when he made one step too many and fell into our client's pool with his  new 4g iphone in his pocket.  He immediately called us but he could not really hear us and we could not hear him.

He called us from a land line when we told him to turn off the phone, go buy a bag of "rice" and put it in.  He did and left it the bag covered completely with rice and 2 days later "presto"

it now works.

Hope this helps someone.”

P.S.  Hopefully you won’t have the opportunity to try this, but if you happen to have success with this tip let me know!
