Guys today it was heavily raining and my N900 got wet , fortunately I've entred a building and turned it off pretty soon,pulled out battery then cleaned with cloth. When I got home I dried it with hairdryer and turned on. everything went fine, device booted but there is a watery spot under the screen on the right..I've turned it off again and placed in a container with rice. Any ideas? will rice help me? or i need to disassemble it?

Thanks
