The development of popular jailbreak tweak NCSettings, which places system toggles within Notification Center, has been discontinued. According to developer JamieD360, he simply does not have enough time anymore to manage the tweak. He will, however, ensure that the tweak remains compatible with future iOS software versions.
NCSettings is an add-on for Notification Center that allows quick access to the following toggles: Wi-Fi, Volume, Brightness, Lock Rotation, Cellular Data, 3G, Vibrate, Silent, Location Services, Auto-Lock, Flash, Private Browsing, Bluetooth, Airplane Mode, and Power. Those power options include Respring, Reboot, and Power Down. Fortunately, there is still the much more popular SBSettings tweak by BigBoss available on Cydia.
