Stephano just pointed out a new theme to me on BlackBerryforums by General Mayhem. The theme is based around the old Ghostbusters movie and has a great nostalgic vibe to it that may appeal to some. So far there is no OTA option but the screenshots above and below should give you a pretty good idea of what it will look like. Thanks again GeneralMayhem!
