Apple has enabled user tracking of its customers once again, with the recently released iOS 6 enabling advertisers to see which apps users have run, and which adverts they've seen – all for the benefit of the users, of course.

The feature wasn't highlighted by Apple at the launch of iOS 6, as Business Insider points out in its detailed rundown, but the new tracking number is important as it enables advertisers to target users, and provides decent enough obfuscation to make switching it off really quite difficult, though those making use of it would question why one would want to turn it off anyway.

The IFA, or Identification For Advertisers, is a random number generated once by the iOS device which is used to uniquely identify that device between applications. The number is available to apps which can send it to their advertising service of choice to pull down new adverts, perhaps based on previous usage of viewing, without sharing the identity of the user or their equipment.

Prior to iOS 5, developers could use the UDID, a unique device identifier which was available to applications. The UDID worked fine, but there was no way to prevent applications reading it and while lots of applications, and advertisers, were benignly making use of the UDID, customers started to get riled about privacy and (after giving developers a decent warning) Apple pulled the plug.
