This tweak is no longer maintained and kept here for legacy reasons. It may have issues with newer versions of iOS, and with certain other tweaks - as it's no longer updated.
This tweak has been superseded by Juice. Juice offers almost unlimited customisation (including a full built in battery editor/designer, support for alkaline themes, and much more), incredible performance, support for the latest and greatest iOS versions and tweaks, and overall a much better experience.
