Might as well try the alcohol and sunshine (AND rice) routine, ESPECIALLY. for cell phones. They have a water sensitive coloring inside that changes color to warn the phone company that you've had it in water, thus voiding the garantee.

My electronic backpacking gear is now all waterproof, to a few feet at least. And some actually float.
i.e.
Garmin Colorado GPS
SteriPen (natch)
Canon digital camera
