First, download the firmware 2.0

Then once the download is complete place the firmware in the Ipod Software Update folder.
Mac OS X :
Library/iTunes/iPod Software Updates
or
Library/iTunes/Mobile Applications
Windows XP :
C:\Documents and Settings\[user name]\Application Data\Apple Computer\iTunes\iPod Software Updates

Windows Vista :
C:\Users\(user name)\AppData\Roaming\Apple Computer\iTunes\iPod Software Updates

Note : these locations are hidden by default in Windows
Check "Show hidden files and folders" in folder options

Once you place the new firmware into the Ipod Software Update Folder go to Itunes and plug your Ipod

Go to the Ipod Screen on Itunes and click "Check For Update" Or "Update" what ever it says.
*Note you may want to backup ipod before you do this*

If you have placed the Ipod firmware 2 that you just downloaded in the correct folder it will prompt you to install the firmware when you click update... Click yes or agree and it should start to install.

Let it install and you now have free firmware 2
