I am still using the N900, and probably will for a long while.

About six months ago, one of my two N900s fell into the toilet (I was going into the shower so the toilet was clean). I quickly pulled it out and tried to towel it off. The screen started fogging up and in a few seconds it finally shut down. I thought, "oh no I should have removed the battery right away". I opened it and removed the battery. It was wet. I turned on the hair dryer and started to blast the phone with hot air. The screen fogged up. I continued to blast it with hot air. The device got so hot I couldn't hold in my hand. I stopped blowing and allowed it to cool for a little bit. Then, I blasted hot air some more.

I don't remember how many times I repeated this exactly, but I am happy to report that the phone survived and has been functioning perfectly since then. What a work horse!
