MM-7400 Got Wet!

Hi, today my mother spilt coffee on my Sanyo MM-7400 cell phone, She immidiatley took out the batterie, after about 5 hours of letting it dry under the sun and hair dryer. I putt the batterie back in and it just keeps vibrating. Even when its off. I need to know is it going to keep doing this, is this some auto dry its trying to shake out the liquid ? can anyone help me PLEASE!!!!

With liquid damage it's hard to say, some are lucky and when the phone dries the phone works ok, but sometimes liquid does managed to get into the phone's circuit and then there's no fix for that...good luck.
