As of iOS 6 Apple is gradually changing the rules for in-app advertising, forcing developers to replace the older Universal Device Identifier (UDID) tracking with a new “Advertising Identifier.” The added bonus to this approach is that iOS 6 users now have the option of opting out of tracking for targeted ads, however Apple has made this feature less than obvious, hiding it away at the bottom of the About screen in the iOS 6 Settings app.
To find the setting, simply open the Settings app, select General and About and then scroll down to the bottom and you should see an “Advertising” button right above “Diagnostics & Usage.” Tapping on this will take you to a page with a single ON/OFF toggle to Limit Ad Tracking.
Apple includes a “Learn More” link at the bottom to provide more information on this feature, explaining that advertising networks are not yet required to use the new iOS 6 Advertising Identifier feature, and hence the use of the word “Limit” rather than “Disable” or “Opt-out,” suggesting that it will not yet completely eliminate ad tracking, but it’s definitely a step in the right direction if you’re concerned about this.
