A21z, one of the things that you might be running into right now, is failure of the components due to corrosion. Like you said, you can live with it, problem is, your iPod may not. The very first thing that I would suggest is to clean your iPod. Use [guide|5825|these instructions] to clean your iPod. They were written for a 3G but do apply to the iPod as well. Use [http://www.ifixit.com/Device/iPod_Touch_4th_Generation#guideList|these guides] to work on your iPod. Once you got it cleaned, reassess the damage, if any.
