Did your ipod overheat when it was connected? This is vital information to ensure that it isn't broken permanently. If it didn't, pry it apart (Note: Look up a video on the proper way to do this) and rube each part that has a sticky residue on it clean with a small amount of rubbing alcohol on a cotton swab. Then, while the ipod is still apart, put it into a bowl of rice. (Note: I prefer cotton, because it is much more absorbent.) Then reassemble it and pray for the best.
