CleanActivity allows you to remove unnecessary buttons from the Activity Menu in iOS 6

  In iOS 6 Apple has implemented a new menu through which we can share content from our iDevices or save content in them, it is called the Activity Menu. This menu has a whole suite of buttons, and some people don't find them all useful, so the tweak CleanActivity took his life. With the help of this tweak we can remove from that menu all the buttons that we don't need, it has a settings menu in the iOS Settings application, where all the changes we can make are listed.

  CleanActivity it is available for free in the repo BigBoss al Cydia.
