If you were just happy that you jailbroke your iPhone using the GreenpoisOn hack iOS 4.2.1 successfully, hang on. There’s a twist in the tale. Apple has apparently introduced a jailbreak detecting API on iOS 4.2.1 which is blocking jailbroken devices from opening ebooks. This inherent API which was supposedly dropped by Apple in iOS 4.0 has found its way back and is blocking the iBooks 1.2.1 app from reading purchased protected DRM content.
The following message is being showed on iOS 4.2.1 devices when trying to open protected DRM content –
“There is a problem with the configuration of your iPhone . Please restore with iTunes and reinstall iBooks.”
The hacker dev community is quite upset with this move from Apple and has criticised saying that it is beginning to attract many to dislike them. Jailbreaking has been deemed legal, so now we have to wait and see if Apple is going to be sued for not allowing purchased content on a jailbroken device.
