1) open all the possible ports n9 is having eg sim port, micro usb..
2) keep n9 in standing position a bit tilted on the screen side.. with sim slot facing up
3) take a blow dryer, fix it at a safe distance form n9.. not too close.. at a safe distance so n9 can get the heat via hot air frm it...
4) keep it running as long as possible...approx 3hrs as much as your dryer can handle.. its cheaper then n9 anyways..
5) hopefully moisture will get released from the top slots..
6) don't turn it on yet..
7) bury it in a pot full of rice... the rice will absorbe all its remaining moisture in 1 or 2 days...
9) turn on your N9.. Hopefully it will Work. "where is 8(I don't like 8)..

GODbless you
