my cat peed on my RAZR V3

I know, that sounds horrible. i have no clue what to do about it now... i tried taking it apart and cleaning it, but i can't do much more than taking the battery out... i tried drying it with a hair dryer, and it still didn't do any good. i turn on the phone, and it thinks the 4 key is being held down... occasionally other numbers will pop up, but its mostly 4. its a new phone, and i am gonna be in big trouble if its seriously messed up. what do i do? i don't have access to any fancy tools to take my phone apart... somebody, please help me save my phone!
