You may not be able to completely shut off Apple’s new iAds system when it shows up on iOS 4 devices in July, but at the very least, you can stop it from using your personal information to tailor ads to you.
Similar in structure to Google’s ad preferences, which allow the user to opt in or out of “interest-based advertising,” Apple on Monday released its own Web-based tool, which, when visited on a device running iOS 4, will opt the user out of the iAds targeting system.
Users must visit oo.apple.com on each iOS 4 device they wish to remove from the program.
While this is a good step to help people feel more protected, the whole “opt out per device” strategy is not as easy as it could be. Why are users not able to opt out for every device tied to their Apple ID, all at once?
