Apple iBooks users who jailbreak their iPhone may find themselves locked out of their own book collection, CNET reports.
Apple has allegedly built a jailbreak checker into iOS version 4 and above to see if someone’s iPhone has been jailbroken with a hack known as greenpois0n, according to the Web site Social Apples.
If the hack is found, then Apple reportedly blocks access to content in the latest version of the iBooks e-reader app.
The unlucky iBooks user who reported the experience on Social Apples ran into the following error when trying to access an e-book on a jailbroken device: “There is a problem with the configuration of your iPhone. Please restore with iTunes and reinstall iBooks.”
