Starting GUI App like from SpringBoard but via SSH
I'm looking for a way to start an App on iOS 4 via SSH, so that it's GUI appears on the device's screen, like starting Apps from SpringBoard. There was a solution from Erica Sadun for iPhone OS 2, but it doesn't seem to work on OS 3 and later:
EricaUtilities -> Program "launch". Run an application from the command line as if it had been launched in Springboard. You must submit the application id, e.g. launch com.apple.Calculator.
Is there a way to do something like this on iOS 4?
Actually I need to reboot the iPhone automatically every day, I think it can be done by launchd (System/Library/LaunchDaemons) and than automatically start a certain GUI-App. Maybe it can be done by launchd also? It didn't work when I tried, that's why I ask, but maybe I did something wrong.
