Well, I have dropped my cellphone in water bunch of times before and all I had to do was to let the phone dry for about a day or two to make it work again. If you dropped your phone in water, you might want to consider dipping it in a bowl of dry rice and the rice will absorb any water remaining in your cellphone.
The most important thing to remember is to avoid heat. That means no hair dryers, ovens, microwaves or extended periods in direct sunlight. While heat will certainly evaporate the moisture, it could also warp components and melt adhesives. Those fragile glues are also why you’ll want to avoid dunking the phone in rubbing alcohol (an oftprescribed tip on the Web). Alcohol is a solvent and can dissolve the internal adhesives. (If you drop your phone in the toilet, it’s okay to wipe the outside with alcohol to disinfect it.)
Here’s a cool device to protect women of Japan while they fart and whatnot…
[A] device called Oto-hime … makes a chirping sound when ladies use the toilet, because Japanese women hate the idea of anyone being able to hear any sounds they make while they go. Before the device was introduced in the 1980s, it seems that female patrons in restraunts would flush the toilet multiple times to mask the sounds, which wasted an incredible amount of water…
Here’s a video of how they work. Just wave your hand over the button and the sound of water will come out of the device, allowing you to do whatever you need to do with without nervousness of people listening to the sounds you make.
