Alright, so I know having a fitbit in some shorts when you jump into a pool is hard to explain, but it happened....a month ago now.  Fortunately, some of my other friends had already ruined their fitbits by getting them wet.  What did I do differently?  When I took the fitbit out of the water, I didn't press the button on the device and then i dropped it in a bag of rice for 3 days before I did push the button.  It was dirty, but it worked.  Everybody else said that their battery wouldn't hold a charge after getting wet, but mine is doing great.
Hope that helps somebody someday.
Adios.
