redsn0w 0.9.10b4 update includes iBooks fix
RedSn0w, the popular jailbreaking tool has been updated to version 0.9.10b4 and now includes the long awaited fix for iBooks not being able to run on jailbroken iOS 5.0.1 devices.
The b4 version of redsn0w incorporates the 5.0.1 fix for iBooks, and also for sporadic problems with launchctl. Thanks to @xvolks for merging the iBooks (sandbox) fix from @comex’s github into the overall corona untether from @pod2g! As usual, you can choose to install the fix either by re-running redsn0w over your existing jailbreak (de-select Cydia if you do that), or by installing the corona package from Cydia (it’s the same set of files no matter which way you choose).
If you’ve previously jailbroken your iPhone/iPad/iPod Touch using redsn0w, all you need to do is re-jailbreak it using 0.9.10b4, but do remember to uncheck the “Install Cydia” option beforehand. Conversely, you can run the latest version of the Corona package (1.0.4) on Cydia in order to use iBooks once again.[via dev-team blog]
