The jailbreak tweak Corona 5.0.1 Untether – which, once installed, can can convert a tethered jailbreak to an untethered jailbreak solution – has recently received a couple of updates.

Both updates were announced by Jay Freeman (@saurik) via Twitter. The first fixes iBooks DRM issues – this something the iPhone Dev-Team corrected in an update to redsn0w recently; the second improves support for the iPhone 4S under iOS 5.0. If your iBooks app isn’t running properly, you can now fix the issue either with Corona or redsn0w.

According to the iPhone Dev-Team:

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).

The new version of Corona is available via Cydia, and redsn0w 0.9.10b5 can be downloaded from the iPhone Dev-Team’s website. Let us now if you apply the iBooks fix to your iOS device in the comments.
