Well,

i once found a Nokia without a battery in a roadside-stream of water... after drying and powering it on it worked flawless...

the real thing you have to worry about will be the water in the cam module. i have no clue as to how get it out. i once had water in the speaker of a very expensive babysitter-device. i never got it out. never. it stayed in there for a year or more. it was toilet water. very nice.

what happens to your leo when it is in contact with water while the battery is connected? do you know that?

well, if not, this is what i know: the electrical current will eventually short some circuits and thus might break them. if you are lucky the shorts will not break anything. if you are not lucky, something will be f****.

then, the energy, metal and water will lead to some "galvanizing" effect i have observed before, meaning, some circuits on the board may build some micro-connections with a whitish coating. what exactly happens there is beyond my knowledge. i have seen it on some devices which had been exposed to water and energy for a while. i could still fix them by scraping (yes, indeed) that off with a micro screw driver, being extremely careful not to harm any print circuit or smd-parts. that is a tough nut to achieve, for real. its not easy.

I am unsure, how the CPU is soldered onto the mainboard. there is a guy here who created some heatsink for those who had broken solderpoints and heat problems. he had said that, if you want to take off the chip you need break it because there is some epoxy around it. that would mean its connections (the little ball solderings) are waterproof. that would already mean you only have to spend attention to the surroundings. that is very relieving.

you might want to check the Internet for a replacement camera module if you don't figure out how to get the water out.

Make sure you keep your impatience under control and don't power on the device with the water still in the cam. it will do damage. the cam has electrical connections too, remember.

If i was in your situation i would assume the phone lost and use it to experiment a little. this will eventually help people here.

what i would do is the following: disassemble completely.

take all parts that can withstand a certain amount of heat and put it in an oven.

power on the oven with not more than 40 degrees Celsius. make sure not to put it under more heat-stress as it will loosen the solderpoints at about 60 degrees i think, maybe even at lower degrees. i am unsure.

warm it up for a while so that excess water dries away fast.

then check the mainboard and other parts for hidden spaces where water could have remained unseen (e.g. the camera).

then check for the witish coating, some hard to see, nearly transparent layers of water and/or soap residue. i am nearly sure that this witish coating i once observed came from high chalk (calcicated) water. this would be removable physically (scraping) or with citric acid and a soft cloth.

now, what to do with the screen? well, unsure here. check for water. if you think its very dry just leave it and connect it.

if it contains water i would probabyl also just try to let it dry. i cannot really advise here since i have not disassembled the hd2 yet.

i only know that replacement screens are not too expensive. you should possibly buy a new one rather then risking to further damage the phone with invisible shorts.

i need to cook for my wife now, hope i could give you some input mate.

good luck with your device. bad story man. bad story...
