If you would like to do this... Please Register or Log in to view images Then using whatever you prefer, go to /System/Library/CoreServices/ There will be a file there named "SystemVersion.plist". Open this file with a text editor (e.g. Notepad) and towards the end of the text change (in my case "1.1.3") to whatever you want. Once your edited SystemVersion.plist has taken the place of the normal one simply disconnet fro your ipod and now in Settings>About, it will have changed. WARNING: This method can be used to install apps on 1.1.3 that require other firmware versions, simply change it to the desired number (1.1.1, 1.1.2...). Also not that i have had any but you may encounter I did not discover this, credit goes to the guy who discovered it as a fix for installing some apps but as far as i know i am first to use this for Customizing.
