Please help with my iPod! I think it broke...?!?

Not sure of what exactly kind of iPod it is ... I think a 3rd generation iPod Nano. a picture of it is at the bottom of this post.

Alright. so I was using my iPod as usually, then randomly, the up volume button started getting really hard to press, to the point where I couldn't turn my volume up anymore. After I looked down at it, I realized there was a crack in it ... after that, it stopped working.

The thing is, although I can't hear the volume [my speakers aren't the issue, I'm sure] I can still see the green light on my iPod, so that's making me think that its not dead just yet.

I tried plugging it into the computer, that didn't help.

Here's a picture of it. http://i42.tinypic.com/dyluh0.jpg
