Spilt water on iphone 4 screen its been 2 days phone won't turn on what should i do?

Added (1). What's messed up inside the phone?

Put in in a tub of uncooked rice for a couple hours. The rice will soak up any moisture left in the phone. This really should have been done immediately after the spilling but it may or may not work now. Hope it gets fixed
