Love the ICS/Jelly Bean Holo theme, but get irritated when you see the Gingerbread Orange/Green images all over the place, especially in non-stock apps?
Use this theme to get a unified ICS look. It will get rid of all Gingerbread assets and replace them with a Holo theme.
Apply the system theme and reboot. Now select my theme & apply.
You may get an error: 'Sorry, this theme is missing assets for your device's screen size'.
Ignore that and apply it anyway and REBOOT.
