Earlier today we showed you the rap by geoh0t, creator of the widely acclaimed iPhone jailbreak greenpois0n and more recently a PS3 jailbreak, now it looks like Apple is battling back. Reportedly, after installing greenpois0n to jailbreak an iPhone running iOS 4.2.1, DRM-protected e-books (via iBooks) are no longer readable.
Since iOS 4.0, iBooks DRM checks have been implemented by Apple. However, not until iOS 4.2.1 have the checks been triggered by jailbreaks. Jailbreaking an iPhone has always carried a risk and while technically legal, as ruled by the Library of Congress last year, ruining an iBooks collection can prove costly.
Now for the good news. The iPhone Dev-Team, creators of another iOS jailbreak “PwnageTool”, have released an update which includes a workaround for iBooks DRM checks in iOS 4.2.1. Developed by comex and pushfix, the update is available now. As far as greenpois0n goes, for now there is no workaround, but rest assure our man geoh0t will come through in the clutch.
Word to the wise: If you currently depend on iBooks, it’s probably best that you refrain from jailbreaking.
