My ipod touch 3g clad in a leather case was in a pocket of my backpack and I guess the zipper wasn't zipped all the way because everything in that pocket was moist, including the ipod touch. Fortunately my ipod is still functioning perfectly EXCEPT the speakers are not working! All i hear is a crackling sound. There is no water damage because the litmus paper is still white. Is there any way for me to get the speakers working again?
