PowerOptions offers you several functions for the locking system of your iDevice

  PowerOptions is a tweak launched last night in Cydia, and with its help you can expand the functionality of the system by which you close your iDevice. When you long press the Power button of your iDevice, an interface will automatically be activated that allows you to close the terminal, this being the only method by which you can do this. PowerOptions modify that interface and in addition to the option to close the iDevice, the tweak also implements the option to perform only a respring or to perform a reboot.

Power Options overrides your top button functionality and gives you 2 more necessity options "breathing & reboot". When you hold down your top button of your phone or iPod you will receive a custom graphic actions sheet that allows you to reboot, breathe or shut down your device. Keep a look out for PowerOptions Pro with more options and the ability to set your own buttons with this tweak. Enjoy this iDeviceDesign Product for free.

  PowerOptions is available for free in Cydia's ModMyi repo, and PowerOptions Pro should be available soon, which brings much more features.
