this is what you do. DO NOT turn it on after it has touched water. turn it off. remove your sim card and put it in a zip lock bag or a air tight container with dry uncooked rice and Desiccant’s. (silica packs). My iphone 3g was submerged in water and in about 3 days of sitting in a container/hot cali sun, it was up and running perfectly.

99.9% change the motherboard is completely fried. Not to mention every single component is most likely useless being under water for that long. If i were you I would sell it “as-is” on eBay and get a new phone.
