Upgraded to iOS 5 recently? Many of our users are complaining that they are facing Activation Mode error on their iPhone, iPad and iPod touch. Inorder to get a sneak preview of iOS5, they had upgraded their iDevice’s to different developer versions of iOS 5. Currently Apple has released iOS 5 to developers only.
Developers can register upto 100 iDevice’s by sign up for Apple’s iOS Developer Program. Inorder to join this exclusive club, developers are charged an annual fee of $99. Like all developer releases, iOS 5 also requires Unique Device Identifiers (UDIDs). How foolish can one be to paying $99 for iOS 5 when OS X Lion upgrade is for $29.99?
Taking advantage of this situation, some developers had started to reselling UDIDs to hungry iOS 5 users for a nominal charge of $5-$10. According to karthikk.net, Apple has started hunting down developers involved in reselling UDIDs. Apple is not only cancelling their develop account but is also disabling devices running to purchased UDID’s.
