iPod touch How do I get the Jan '08 software update back?

Woops, I didn't know that restoring my iPod would erase the January '08 software update, and now I can't find any information on getting it back! How do I go about doing this?

Sorry about that, I didn't realize there was a topic already open (https://forums.macrumors.com/threads/448398/). A mod can lock this if they wish to do so.
