The desiccant suggestions are stupid. Anyone remotely tied to electronics design and manufacturing will correctly tell you to bake the thing. That's exactly what happens to all the components inside that thing before they are assembled. Moisture inside a PCB and components will get hot and blister during soldering, water is a dirty contaminant, etc. These things are almost always baked for a long time at low temps, then vacuum packed with desiccants before shipping. I'd recommend ~200 degrees F, ~8 hours, as a pretty good guess.
Be certain to turn off the phone. DON'T power it up!!!! Wipe all surface water off with a towel. Take a vacuum nozzle and vacuum off any water that you can. Place the phone in a ziplock with a cup of white rice (Teddy Kennedy used this method to keep his cocaine moisture free) and seal for 24 hours. Now, you have adequately removed as much water as you can. Power up and assess the damage. The worst thing you can do is power up the phone while it's wet.
I agree, the Galaxy is the better phone by far but... I have to say I prefer my iPhone simply because I know how to use it well. Once I get into something, I'm good. Also the reason why I'll be good with the same one for the next five years. I'm easy like that.
