Requires iOS 4.0 or higher
Allows you to use activator to activate the in-call status bar, then exit any certain app, and do as you please, tap the bar to go back to the app immediately, if you don't want to go back and you change you mind use the same activator action to dismiss the bar, i suggest using status bar "swipe down" as it makes things a lot easier.
