sonya7175, two things first. Get it out of the rice. It does not work and is an absolute waste of time and good rice. All this does is give you a false sense that you are doing something, in the meantime your iPod will continue to corrode. Second thing is stop charging or trying to turn your iPod on. This can damage it further by creating more of a shortcircuit.
At minimum you will have to replace the battery and the hard drive. Those two things do not like water at all. Disassemble your iPod using these guides Clean the logic board with isopropyl alcohol (+90%) and check for missing/burned components. After you cleaned is properly, replace the battery. you can check your hard drive by using a Zif-to-USB adapter and see if it does still function. Most likely you will have to replace it. When you replace it you will of course lose your music files, unless you backed those up prior to the damage. After that, reassemble and re-evaluate. Right now it is strictly academics since we do not know what the inside looks like.
