Reduce personalization of ads(iPhone)

             Your phone saves data about its geographical location, and you want to prevent this data being misused.

            At its default setting, every iPhone records location data which is then sent to Apple's servers for various purposes. As per information provided by Apple, this data is used for the intelligent iAd advertising platform amongst other things. You can however disable the collection of such data as well as the advertisements. Since the update to iOS 4.3.3, location data is no longer saved if geolocation is deactivated. In order to disable the advertisements, go to oo.apple.com from the phone's browser. This unregisters your device from the iAd platform so the ads you see after that are no longer as personalized. If you have multiple iOS devices, you will need to perform the described process for each one individually. Re-registration is also possible using the same method.
               There are also tools which can read and show you your phone's stored geolocation data. You will be surprised to know how comprehensively and accurately your iPhone logs movement. iPhone Tracker for Mac OS has been around for a while now. You can download it from petewarden.github.com/iPhoneTracker/#1. A Windows version is available at huseyint.com/iPhoneTrackerWin. Both tracker tools are very easy to install and operate. Of course, an iPhone is a basic pre-requisite for using these programs.
