Mac/iOS: Newstand is one of the more annoying app icons on iOS if you don't use it, because you can't just hide it away in a folder. Initially, the only way to hide it was with some finger kung-fu, but StifleStand does it in one click.
All you have to do is run StifleStand, connect your iPhone or iPad, and click "Hide Newstand" when your device is recognised. StifleStand then creates a folder for the Newstand. You don't need to jailbreak or worry about getting the timing right to hide the icon. If you are jailbroken and want a solution to completely get rid of the Newstand icon, search for NoNewsIsGoodNews in Cydia.
