What happened?

This app USED to work great, but I cannot place any ghosts after the last update. Ive uninstalled, rebooted, then reinstalled and there is no way I can get it to work on my iPhone 3GS. Ill give it 3 because of how it used to work, but I hope for a update soon that makes it useable again.
