But if you don’t like iAd appearing on your iDevice (iPhone, iPod Touch, iPad) and find it annoying, then there is an easy way to disable these ads on your device. The Firewall IP developer Yller has created a simple file called iADkiller.deb for iOS4 devices which will disable Apple’s iAds in an app. Installing the iADkiller is very simple, but your iPhone must be jailbroken in order to use the app. Just follow as described below (thanks to gadgetsdna) Now whenever you run any app on iPhone, iPad or iPod Touch, those iAd won’t appear.
