I just got this phone and installed the Go Launcher. and I want the option to where you click on your "home" button you get the option to go to your phones default or the go launcher. Mine set itself to Go when I first installed it I can't get the option to choose. And in the settings it has "no defaults set" greyed out but IT IS the default and I DON'T want it to be the default. How do I fix it? Thanks.
