If you dropped your phone in the toilet or the beach or anything that will make the Nokia phone wet, leave it turned off overnight in a bowl of uncooked rice. Huh? rice? Yes, rice, the uncooked one. Uncooked rice sucks out moisture.
One of just a few uses of rice. Only this time it's the healing qualities of rice. Some Nokia mobile phone enthusisasts also swears on the healing qualities of breakfast cereals and oatmeals.
