There is a black spot on the top part of my ipod touch. The day before, I dropped it into water. To try to fix the water damage, I put the ipod into the oven at 170 degrees and left it in there for about 2 hours. After I took it out, the ipod seemed to work fine except the black spots were there. Any slolutions?
