The Chronic Dev Team has released Greenpois0n RC6.1, a new version of their ‘untethered’ iOS 4.2.1 jailbreak tool which now includes an update that disables Apple’s means of protecting the iBooks application from jailbreakers.

In a recent update to its iBooks application, Apple introduced a mechanism that caused jailbreakers to lose access to DRM (Digital Rights Management) protected iBooks.

The relentless teams of hackers filling their void by breaking into Apple’s software locks have been busy updating their jailbreak tools on a weekly basis, sometimes even twice a week if necessary, to support the faithful iOS jailbreak community.

Following in on the iPhone Dev Team's footsteps, Chronic Dev is pleased to introduce Greenpois0n 1.0 RC6.1 for Mac OS X and Windows.

Supporting iPod Touch 2G, 3G, 4G, the iPad, iPhone 3GS, iPhone 4, the Verizon iPhone 4 (iOS 4.2.6), and even the Apple TV, this version of Greenpois0n also comes with the aforementioned iBooks fix.

The changelog accompanying the Greenpois0n download reads:

> Changelog:

- RC6.1: comex 'hunnypot' iBooks fix, don't overwrite animate if it already exist   - RC6: Apple TV 2 support, fixed emulators compatibility issues with greenpois0n   - RC5.4: Verizon iPhone 4 is now supported !

In related news, the iPhone Dev Team has been allowed to include the Greenpois0n ‘untethered’ exploit into its own PwnageTool jailbreak application.

Arguably the most reliable of all jailbreak solutions, PwnageTool 4.2 now provides iOS 4.2.1 devices with a proper ‘untethered’ jailbreak, while also preserving their baseband for carrier unlocks.
