Son of a @**$&#^

Drooped mine in three weeks after I got it in 2012.
Had to suppress the "ewww" reflex, and reached in for it almost immediately.
Took off the battery cover, removed the battery and let it dry.
Surprisingly it wasn't wet inside.
2 hours later, put it back together and it's still my phone six years later.

if you let it sit submerged, that's when you get the water inside.
