Take it apart as much as you can and try and dry it out asap with tissue and then placing in a warm dry area. Give it a bit if time there and it might just work on re-boot. If not, it may well have had it.
You let it sit in a bowl of rice. The rice will absorb all of the water.
Get a new one.
I do not think that you can fix them. If the keypad isn't responding then you will have to take it to a local mobile phone shop, or your supplier.

Put it in the microwave on full heat for 7 minutes. This will dry the water out and levae your phone intact..... Mostly.
Electronics in general are "ruined" once they fall in water. Try the link Fix a cell phone that fell into water.
You take out the battery, and put it in a jar of rice for 24-48 hours.
Let the water drain out of it. Then let it dry out for 3 or 4 days and hope it works. It all depends on how much water got into the phone. If you are able to open it up it will speed up the drying time.
