Unusable UDID in new ios7 (with FFFFFFFF prefix)
Solution 1
Yes. The "FFFFFFFF" UDIDs are wrong. This seems due to the fact that the UDID is now considered a Privacy Topic and thus Apps are not allowed anymore to retrieve them... and iOS returns an obfuscated UDID if called and precedes the first digits with FFFFFFFF. So I guess some of your clients got the UDID via an App on the device.
See here: https://stackoverflow.com/a/19032885/2580805 "The only & unique method to get UDID under iOS7 is to plug your device to a computer, launch iTunes (or Xcode) and copy the displayed UDID."
But I have to add: there are at least two more options:
- Our testers that provided their UDID by registering their devices via TestFlightApp.com also got non-FFFFFFFF UDIDs that worked.
- Testers can surf with their device's Safari to: http://udid.io - this site installs a (temporary!) profile on the device which allows it to show the user a working UDID for copy & paste.
Solution 2
you can use to get the proper UDID of the device(s) the followings:
- iTunes application;
- the Xcode Organiser option;
or online:
- http://get.udid.io (the actual device needs to open this site);
Solution 3
get UDID through Organizer
or iTunes
. if you are getting it through 3rd party software, that might be wrong.
For Organizer, press Command+Shift+2
on XCode
