Motorola V710

I recently dropped my phone in a puddle and the bottom half of it was submerged. The phone still kinda works except its not really charging and I think its about to go to its grave for good. Anyway when I finally got it to go on instead of saying 'contacts' in the lower right hand corner of the screen it says 'radio'. When i push this button thhe left and right home keys turn into next buttons for the radio and under where it says Verizon Wireless in the top left it says 88.9 FM. If i push left or right it changes station. I can't hear any music and I tried plugging in headphones but music still didnt come out. Where did this glitch come from and does anyone know anything about it?
