hello, I have been playing around with SpringBoard Hooking thanks to some of the tutorials on this site. i have the ability hi-jack the lock (power) button so that when it is pressed a UIAlert pops up. What I would like to do, is have an app launch when this button is pressed. I looked through the SpringBoard.h class dump and couldn't find a way to do this. I also tried using an app URL to try something like: [[UIApplication sharedApplication] openURL: [NSURL URLWithString: @"myapp://"]]; This method works when called from an app already running, however when I press the lock button with no apps running, the home screen freezes. Any thoughts or suggestions? Thank You.
