What kind of information leaks to the advertisers though? Do they have enough information to reaquire you (match your new ID to your old profile data) after a reset?<p>I'm sure that most advertisers can do this to some extent on the web, and use this to get around the users' ability to reset cookies.
Could someone make an app that resets this with a single button push (without navigating to it), or perhaps an app that runs in the background and changes the ID every hour or day?
