New day, new cydia tweak. ClearLockNotifications allows you to delete the notifications of a specific application on the lock screen, without unlocking the iPhone, which by default is impossible. To clear all notifications click on the icon of the application, you have to slide to open the notification, an icon with an "X" with which you can make it go away. You can download it for free on BigBoss repo, Cydia. For more information check the video embedded below.
