Nokia keeps coming out with a lot of editions be it a Music Edition, Internet Edition, Navi Pack and so on. Here is someone who is turning his N95-1 into a water edition! Please keep in mind that doing this at home is seriously injurious to your phone’s health and should NOT be done!
In case if your phone ever does get wet, the best bet is to take the battery out immediately, to prevent a short circuit and let the phone dry for as long as possible and only then turn in on, much later. The wait will be worth it!
