We have got information through some reliable sources that PwnageTool v4.2 is being developed to bring untethered jailbreak support for all idevices on iOS 4.2.1.
The next update of Pwnagetool will also fix the iBooks app issue on iOS 4.2.1 jailbroken deivce which doesn’t allow users to open rightfully purchased iBooks.
For those who don’t know, Apple has included a script in iBooks v1.2.1 which detects the jailbreak state of the device and prevents opening a book purchased from the iBookstore.
Earlier today Comex tweeted that he has found the cause behind this problem and is working on the fix.
Later, MuscleNerd, the key member of iPhone Dev Team also confirmed the fix.
Since Greenpois0n jailbreak tool for iOS 4.2.1 is not open-sourced yet, it seems Comex will implement this fix in PwnageTool 4.2.
Update: Wizdaz, who seems to be very close to Jailbreak Authors’ community, also confirms the working on PwnageTool 4.2.
