Greenpois0n Jailbroken iPads and iPhones May Have Problems with iBooks

by on February 16th, 2011

Apple appears to be taking a stance against jailbroken iPads and iPhones.

According to the Social Apples blog, iPhones and iPads running the latest iOS firmware contain a “jailbreak check” that automatically detects when the devices have been unlocked using the greenpoisOn jailbreak kit. Jailbroken devices that attempt to load content using the iBooks application, even legally acquired e-books display an error message that reads: “There is a problem with the configuration of your iPhone. Please restore with iTunes and reinstall iBooks.”

An iPhone hacker, known as pushfix on Twitter, noted that the iBooks DRM checks have actually been in iOS since version 4.0, but weren’t triggered by earlier jailbreaks. However, jailbreak tools like greenpoisOn have continued to disable more and more of Apple’s built-in security mechanisms. I guess this is Apple’s way of trying to regain control. “Comex,” a hacker with the iPhone Dev Team, said in a Twitter post that “iBooks drops an improperly signed binary, tries to execute it, and if it works concludes that the device is jailbroken and refuses to open the book.”

For other “jailbreak” users, there is a new version of Pwnage Tool that will jailbreak your device using the “feedface” exploit developed by Chronic Dev. This new jailbreak fixes the iBooks issue. There will also be Cydia packages available to fix the iBooks jailbreak checks . Now that @comex and @pushfix patched the problem, I’m sure it won’t be long to be ported over to greenpoisOn as well.

What do you think about this?
