Water Damage

[JPT]

So.... A few days ago, I accidentally dropped my 3GS 16GB in water... I left it in dry rice for about 3 or so days and turned it on. It still works, but it seems when I am on battery mode it likes to shut down completely. Usually when it starts to shut down it gets faster every time and eventually won't even start. It almost seems like it's a power/battery problem as it just outright shuts down. It will typically shut down after I do something, for instance if I load up iBooks or a book in iBooks... Or even while using TextFree.

Before spending $20+ on a hunch at iFixit for a new battery, I figured I'd see if anyone more knowledgeable could further pinpoint the problem? Also, would I be able to bring it into an Apple Store to have them check it out? If I can, will it cost?

Oh, and just a suggestion: Don't drop your electronics in water... It's not fun

It has water sensors, so apple will detect it was soaked in water.
iFixit is the way to go to disassembling it and drying it, but I believe that if there is some damage there is nothing else to do about it, unless you replace what is defective.
Apple can sell you a replacement for ~$200 I think, not sure about the price with the iPhone 4, but there is a special price for replacing damaged phones (if the Genius doesn't offer it ask for the manager).
