My friend pushed me into the pool with an N97 still in my pocket...

Got out of the pool, removed the battery and attempt to dry most of it out using tissues to suck up the water. Then sticked it in rice for 3 days. Worked fine after that!

My advice is whenever you get into such similar situation, it's important to remove the battery out straight away to prevent internal short-circuiting. Stick it in rice for at least 3 days. Don't dry it with hairdryer, that thing can get pretty hot and damage the internals.

Water cannot do damage to electronics without power/electric, the moisture is what kills it, water + electric don't go well together if the device is then dry up completely, it will behave exactly the same as when you first bought it.

I did an experiment back in school, stick a laptop into the pool, then attempt to dry it completely, stick it in rice for a month. We then put the battery back in and attempt to turn it on, it worked fine.

/me start's to cry...why would you do that to such an awesome phone...

I KNOW!!! I was yelling at my computer screen "DONT DO THAT! STOP IT!!! YOU'RE HURTING IT!!!!!" *sniffle sniffle* That n900 never hurt anyone!

"Note: From our experience, we would highly recommend that you avoid exposing your Nokia N900 in heavy rainy weather."



Well... duh. What's next, tying the N900 to a lightning rod, fry it, then highly recommend not to expose it electrical storms?

Seriously, if you want to break a device for fun, go ahead, but don't mask it as pseudo-useful tests.

Pure water yes, high ph tap water and low ph rain not so much.
The impurities left behind when this kind of water evaporates will cause problems later on. Some of these residuals are also conductive to electricity.
The short answer, always keep electronics dry.
...and as you said, if an accident does occur, resit the urge to turn it on "to see if it still works" and remove the battery or power source immediately.
A chaser of denatured alcohol before drying has also been known to help in some cases. However this may also attack glues and soft plastic components.

I found the tests useful. They help show which areas of the N900 should be protected with various screen protectors/cases, how it reacts to dust, and water - all things that happen in real life. Sure, the results of the freezing water/snow test is probably as expected, but it clearly survived the less strenuous test beforehand. Suppose the test showed that a single drop of water fried the keyboard/affected the screen - that would be useful information.

He conducted the tests because his N900 was defective, as mentioned in the first video.

plzzzzz tehkseven.net, leave the phone die in peace

Well, as we've seen, the rice trick worked and the phone survived (http://www.youtube.com/watch?v=y030QJbaUus)... it even made a nice video of the trip from UK to CAN (http://www.youtube.com/watch?v=oE-_QN7p--c)... =)
