Apple is beginning to reject app submissions which access a device’s UDID, according to a report by Mashable.

You just can’t beat a good privacy scare, and the one surrounding the use of UDIDs, or Unique Device Identifiers is the current biggie. Used by developers and advertising companies, UDIDs allow tracking of individual devices which has the privacy conscious up in arms.

With Apple now reportedly rejecting apps that use UDIDs, developers, ad. agencies and anyone else who may legitimately use UDIDs will need to re-write their apps to remove the feature…

Mashable’s report suggests that two of Apple’s ten review teams are already rejecting apps that use a device’s UDID, and that the other teams will come online over time, leading to all Apple’s testers eventually rejecting such apps.

Apple is said to be accelerating the removal of UDID-using apps from its App Store due to increasing pressure from all angles, though developers will understandably not be quite so keen on the move. No obvious replacement for the UDID has been touted just yet, with developers very much left to their own devices in order to keep their apps functioning as they do now. Apple, for its part, has been characteristically dev-unfriendly about the whole situation.

Are you an iOS app developer whose app relies on UDIDs to function? What will you be doing to replace them? Let us know in the comments.

  • hashed mac address.

  • I for one am not a fan of this move. I use a UDID faker to allow playing multiple accounts on the same game. If the games have to use something else to id your device for your account i may not be able to do this anymore.

  • The privacy conscious starts moaning, everyone else starts groaning.

  • if it is uses accounts…just create another one instead of changing udid and clone the app. easier, isn’t it?

    • Some games that works with others it doesn’t. Guess we will just have to wait to see.

  • Sounds like whatsapp is going to start supporting iPods and iPads… Sweet…

    • You don’t need a UDID to identify device type. I know there’s a plist in the app somewhere that specifically says which devices and software versions the app will support. If your device isn’t on the list, iTunes simply won’t let you install it.

      • Yes, but If you install it some other way (like ifunbox) it won’t be able to identify

  • $25 iTunes gift card for $20. Payment is through PayPal if anyone is intrested.

  • Wonder what tapulous will do now

    there is no need to individually track handsets. sure it’s great for ads, but apps won’t lose function over this.

  • Bummer. In classroom scenarios UDID was the only identifier to nail down a specific device no matter what happened on the software side.

    Replacing this by certs will be a major overhaul, and cost quite a bit of money.

    Big problem for me, too, in data acquisition. We need to track individual devices, could care less about who the user is in a lot of cases. That’s really too bad because customers that have already been using the UDID may have to rework their listeners, change items in their databases, etc.
