Just search 'UISettings repo'. Repo is the word you're looking for.

This is the repo: http://cydia.myrepospace.com/ios5beta

Just as an FYI, SBSettings is now working for iOS 5. There is an option for the standalone window as well as having it included in Notification Center. WAY more options than UISettings and ability to theme it. Check out the Apple.com HD SBSettings theme. Looks killer.
