Re:Apple phasing out developer access to the UDID in iOS 5 by incosta on Saturday August 20, 2011 @02:18AM (#2905977)
I have been using UDID to track on how many physical devices my app has been installed. In part - to see if there is any piracy (a spike in new devices would certainly mean something is going on).

If Apple removes support for UDID completely, I will have no way to track this information. Generating unique ids randomly will result in new ID being created when app is deleted and then reinstalled (something that happens all the time with iPhone apps). Are there going to be other ways to create unique ID based on some hardware specs, or Apple will provide a new function call?
