ClickOnce is an app that adds a floating Home Button to your screen. When you install ClickOnce…it automatically adds a Home Button icon on your SpringBoard (there is no app on your SpringBoard, just the Home Button icon). You can drag the Home Button anywhere on your screen. It will stay on the screen no matter what app you have open. However, I’m not really sure what the purpose of the app is. When you tap it, it brings you back to your SpringBoard but, you could just tap your Home Button to do that. It doesn’t restart your SpringBoard…just brings you back to it if you are in a application. If anyone has any ideas, let me know in the comments. Also, because there is no actual app on the SpringBoard…the only way to get rid of the icon is to uninstall the app. It would be cool if there was an option to turn it on or off. Despite all that…I must say, it does work very smoothly. It doesn’t seem to interfere with other apps which is great! ClickOnce is available through the iPhoneCake source.
