After a long wait of approximately three months, the owners of iPhone 4S and iPad 2 were finally gifted with an untethered jailbreak for their devices. Thanks to the renowned French iOS hacker Pod2g and his Dream Team of jailbreakers, all technical snags blocking the public distribution of the untethered jailbreak for iOS 5 were successfully overcome.

So now we have an untethered jailbreak meant for all devices on iOS 5. Apart from that Apple has also come out with an updated iBooks that offers more engaging content. The company recently announced a number of new initiatives focusing on the education sector, which directly relates to the use of iBooks. The initiatives, no doubt, will promote many more downloads of the free-of-charge application, Redmond Pie reported.

However, there is a catch. Apple, in order to make things a little more complicated, has included some safety measures, due to which, certain applications would crash immediately after launching a jailbroken device. iBooks is one of those applications.

iBooks issues have reportedly been causing problems with books protected by Digital Rights Management (DRM) technologies. According to some users, images and text are displaying incorrectly and sometimes randomly disappear when reading or viewing books that are protected by DRM.

Developer PlanetBeing, who made a successful return to the jailbreaking scene with his useful contribution to the A5 untethered jailbreak, appears to be working on rectifying the iBooks issues.

Hi, I heard some great news from IRC. @planetbeing has fixed Corona issues with iBooks DRMd books. Corona 1.0.6 to be released soon, Pod2g tweeted on Sunday.

While version 1.0.6 of Corona is apparently in the process of being pushed to Cydia, an updated version of Redsn0w (0.9.10b5) for both Mac OS X and Windows has just been released to fix the randomly occurring DRM bug on iBooks after iOS 5.0.1 untethered jailbreak (on A4 device only).

The users who've already jailbroken their devices with Redsn0w should note that they just need to re-run Redsn0w over the existing jailbreak. Users must make sure that they uncheck Install Cydia option.

Once the Corona 1.0.6 is available, it will also have the same effect.

Here are the download links to Redsn0w 0.9.10b5 for Windows and Mac:
