Funny, my coworker was about nipple high in lake michigan for about 2 minutes- with his iPhone safely in it's leather holster on his belt. Funny thing is that his works great, though it smells a little now. lol
Tip for next time: If mobile is not off already, IMMEDIATELY force it off, (with other mobiles, remove battery immediately). And leave it off for at minimum 2 days. If you can, disassemble the mobile completely and let everything air dry for minimum 2 days. It may work, it most likely will not. (maybe) lol. Things like putting it in or near NEW (not used hahaha) cat litter are popular. Also, things like using pure alcohol (though I don't recommend) are not so common, but are used. The ultimate precaution: Never have your iphone on you when you are near water
