When I first got my Defy I was confident enough (still having return warranty) to stir some cocktails with it to prove to my workmates it was water-proof.
Recently I got it back from a complete overhaul & repair due to the speaker bug and button backlights not working, and in the process the rubber lining of the battery compartment was also exchanged. After a short kajak tour where I had confidently kept it in my pants pocket that had gotten fairly wet but never submerged into water I noticed I heard the other end only very silently, and when trying to charge it constantly toggled the connection, but I still did not think of anything bad. Only the next morning I noticed foggy spots underneath the screen, and when I took out the battery there were a few tiny drops of water inside!
Luckily, after drying it completely everything still seems to work, so I was either pretty lucky or the Defy (while obviously not 100% water-tight) is rather water-resistant
