This tweak removes the "X" when uninstalling an iPhone app. Good for pranking your friends and preventing accidental app removal.
No Uninstall requires iOS 4 or higher (got that wrong in the video -- sorry!).
You can do this on a stock iPhone via the Restriction Settings, but if you're running an older version of the OS that doesn't support the app deletion restriction -- or you just want to have some fun at a friend's expense -- give No Uninstall a try.
