Slightly wet iPod is now completely crazy

Hi, here is my problem :

I got my iPod slightly (barely) wet (it was in my bag wich fell in a puddle of water)

I left it to dry for about 5 days.

Now i Have these problems.

First one : Battery dies in less then a day. (the iPod is 4 months old)

Second one : each time I turn it off, or if it dies, when I turn it back on and I try to play some music, I get this message : Please wait wile your library is being updated (something like that). And then all my music and apps are erased but the iPod still tells me that most of the memory is taken.

Each time it does that I have to restore it to its original settings and resync everything.

Third problem, started occuring maybe a month or two later : When my headphones are plugged in the iPod plays both on external speakers and headphones.

I tried sending it back to apple but they don't wanna repair it cause they say it has got some water in it.

However, i'm not sure that the water is the problem.

1:It was realy barely wet, probably more humidity than actual water.

2:I'm not a 100% sure but i think the battery and library problem was an issue before it got wet. I told that to apple but they won't care, obviously.

Any suggestion ? would jail breaking it solve the problem?

Thanks
