They even make special waterproof cases for phones (which are basically heavy-duty ziplocks with a better seal), some of which are designed to be used with flip phones.
Distilled water would be safer than tap water for re-dunking or cleaning, but that's still probably a last resort.
There are, as it turns out, a number of ruggedized phones out there, specifically designed to be waterproof and shockproof; here's a couple I found just poking around (looking for more serious cases, actually, which for some reason seem to be harder to find, though they make them for iPods): http://www.biggtech.com/mobile/a-waterproof-shockproof-and-dustproof-mobilephone-samsung-b1200_159.html http://www.biggtech.com/mobile/seals-vr7-phone-is-truly-rugged-has-lot-of-features-and-is-handy-in-emergency-situations_3316.html
Those are both GSM, so they'd work on AT&T or T-Mobile; if you have Verizon or Sprint (I can't remember), I'm sure there are rugged CDMA phones available, too.
