After I successfully downloaded "Supreme Preferences for iTouch" from Cydia, I found that it did not appear on WinterBoard. I came across a manual installation of the tweak, reading the "how to install" directions carefully, and it appeared on WinterBoard. I set the theme and resprung. However, my Preferences.app was exactly the same as it was before. I still don't understand what the problem is. Help would be appreciated.
