How much video RAM does an iPod touch have?

As for total RAM, the latest iPod Touch 4G has 256MB, whereas the previous models have less. I doubt there is separate video ram but it is a small amou8nt if any. I'd guess it just uses a small portion of the flash RAM. That is probably part of the reason the actual capacity is less than stated because some is probably allotted for graphics and the like.

I'm just guessing here but that's what I'd go with
