You need space to install iOS 4 somewhere on you iPod. It'll take away a few hundred mb.

We've already addressed that.

I seem to remember reading somewhere that actual formatted capacity is in GiB, that is, 1 GB on an iPod is only 1000 MB. Each of those Megabytes is only 1000 KB, and so on. That reduces size, making any change much more significant.
