Yesterday we brought you news of a new program called "StifleStand" that allows iDevice users on iOS 6.0 to hide their Newsstand app in a folder. As of yesterday this program was only available for Mac users. Today it became available for PC users as well. You can download here StifleStand Download, then right click the file and Run as Administrator. Some users are reporting issues w/ the program simply not working. From what we've read... resetting your Homscreen layout, first, does the trick.
