CCSystemStatus is a new Cydia tweak that takes advantage of iOS 7’s Control Center to quickly display useful system information. The tweak displays the info into pages, the first page showing you the WiFI’s IP address, cellular data IP address, free memory and average system load. If you swipe to the next page you’ll be able to see the Wi-Fi network name (SSID), your Wi-Fi MAC address, the amount of free space in the “/” directory, and the amount of free space in the “/var” directory.
Via CCSystemStatus’ dedicated preferance pane in the Settings.app you can enable or disable the tweak and move its position in Control Center.
CCSystemStatus supports only iPhones and iPod Touches for now and it is available for free on Cydia via BigBoss repo
