With the release of iOS 6, Apple replaced its controversial unique device identifier system (or UDID) with the Advertising Identifier. It’s a non-permanent, non-personal, device identifier, that advertising networks use to track your behavior.

Since its introduction, users who don’t like targeted advertisements have had the ability to limit ad tracking via a toggle in the Settings application. And in iOS 6.1, users will gain the ability to reset their Advertising Identifier as well…

Apple seeded beta 2 of iOS 6.1 today. And among other changes, the release notes point to a new button in the Advertising section of iOS labeled Reset Advertising Identifier. It’s kind of like resetting your browser history, but for targeted ads.

“In iOS 6.1, a new Reset Advertising Identifier button has been added to Advertising Settings. This button resets the Advertising Identifier so that future requests will return a different value.”

It’s worth noting that the first beta of iOS 6.1 actually has this button too. It’s a nice little addition that should help keep personal ads more relevant.

Thanks Jacob!

    so if i want ads blocked and not tracking me. Should this be turned off or on?

    it confuses me

    • On. It says “limit” so to limit it should be on.

    How about no ads at all? When I’m paying almost 900 for my iPhone, the last thing I want to see are ads.

      try AdBlocker from cydia if you can. Works in most apps. Pretty efficient tweak.

        used to have it on my 4S, it was pretty good. Hopefully the iPhone 5 JB is making good progress.

  • There’s a significant update to the music interface upon selecting an artist, and then album — you’ll notice the tracks and their time are surrounded by a bigger rectangle. Bad description, I know; see for yourselves!

  • There is a new welcome pass in Passbook.
