Download Greenpois0n RC6.1 4.2.1 Jailbreak With iBooks & Apple TV2G Wifi Fix


by casey on February 18, 2011

Chronic Dev Team has released another updated version of greenpois0n untethered iOS 4.2.1 jailbreak tool. The new version is Greenpois0n RC6.1 and is released specifically to fix iBooks restriction for jailbroken devices and Apple TV2G Wi-Fi. Rest of the features in this versions are same.

For those who are unaware of the iBooks restriction, the version 1.2.1 of the iBooks denies to open books on the phones that are jailbroken. It is because Apple has implemented some anti jailbreaking tricks in it. iBooks is implemented with a process which involves the running of unsigned code attempts. These type of attempts are only executed by the jailbroken phones. So it will detect that you are using a jailbroken iPhone and will prompt you a message to restore your iPhone device.

Normal phones will not execute a small code run by Apple on your device when you try to access iBooks. However jailbroken iPhones by default allows this code to run, thus help Apple to figure it out that you are using a jailbroken iPhone.

Of course you have to buy the books whether you have a jailbroken device or not. But Apple has implemented this obstacle specifically for the jailbroken device owners.
