(9 Colors Option) Apple iPod Touch 3rd Generation Silicone skin case cover for iPod Touch 2G 3G, iTouch 8GB, 16GB, 32GB, 64GB
I got this for my ipod touch 3g and it works great.  I think it might be a little loose but it's fine for me.  If you're looking for something that is tight around it this is not the case for you.
