Where they talk about how hard it is to disable iOS ad tracking.
Where they talk about how hard it is to disable iOS ad tracking.
As mentioned in another comment, the setting was buried in IOS 6, in iOS 7 it is in the Privacy section, has a link to a page that explains what the setting can and can't do (you still get ads but they won't be as targeted) and also let's you manually reset the advertising identifier at any time.
I'm not aware of anything similar or better on any platform.
