LockScreen Multitasking brings the possibility to close applications from LockScreen

   LockScreen Multitasking is a new tweak developed for iDevice owners that brings the possibility to close applications open in the background right from the LockScreen. The tweak changes the way the iOS task switcher is displayed so that the limitation that prevents its opening in the LockScreen is now removed. To open the task switcher in the LockScreen, you just need to double-press the Home button and you will have all the applications open in the background displayed. Considering that this action is normally used to activate the camera open button, now that button is always displayed in the LockScreen.

   LockScreen Multitasking is available for free in Cydia in the ModMyi repo and is ONLY compatible with iOS 5.
