Lol, this is my OP (Which was posted before yours) that I was talking about in your post. And if you read a few posts up it will show you how to get Game Launcher back.Already addressed this in a past forum. See link. There is no Game Launcher for AT&T variants. See forum link on how to get to Game Booster.
