Activator is an awesome jailbreak tweak by Ryan Petrich that you probably already know about. For those who’re new to jailbreaking, Activator lets you assign various actions that get called when a certain event, selected by you, occurs. The trigger can be a gesture, a tap on a specific area, the press of a button, a change of charging state or a bunch of other options. The “actions” list is equally diverse, letting you launch apps, toggle settings and is extensible via tweaks on Cydia.
