The Apple Message App comes pre-installed on iOS 5.
iOS 5 is only available to iPod Touch 3rd Generation and Above. If you are eligible, plug in your iPod into iTunes and it should prompt you to upgrade to iOS 5.
You can update it to iOS 5 the same way you update it to any other iOS version. The 4th generation (and indeed the 3rd generation) iPod Touch can be updated to iOS 5.

No it did not. It had IOS 6. But you can get IOS 7 on it. Also when IOS 7 came out they put it on the iPod 5 in stores.
Well there is no such thing as IOS 6 yet. So far its IOS 5.1 i think and siri is only available on the apple iphone 4s. No other devices have siri and there is no app or update for it
