Smart banners show in the Safari app when you visit a website that has an application available in the App Store. Services like YouTube, for example, will display a banner prompting users to launch the native app when YouTube.com is visited in Safari under iOS 6 (as you can see in the above image).
Not-So-Smart stops this from happening. Once the jailbreak tweak has been downloaded and installed, users will find that smart banners no longer appear in the Safari app. It’s as simple as that.
For more information on the jailbreak tweak, take a look at our video walkthrough. Alternatively, you can download Not-So-Smart yourself – currently, it’s available in the Cydia Store for free (via the BigBoss repository).
