mine has taken a dive too

i instantly took out the battery, dropped the lot in a bowl of rice for 20 mins or so. the took the hair dryer and gave it much hot air (mostly from the front as i thought the N900 would be tougher from the front). back in the rice bowl, and after that more hot air (don't overdo that too much heat can be harmful too ofcourse)

altho my n900 gave only a short swimming demonstration, when i turned it on i saw some blur for a while but after that its functions came back one after another and it has been functioning OK after that. i even have got service for the usb-port problem after that (altho i positively have the same set now i dunno if they have swapped the motherboard)
