A couple days ago, RedSn0w was updated to fix the iBooks DRM issue where some images wouldn’t display properly, or wouldn’t even display at all. At the time, we noted that a Corona update shouldn’t be too far out.
Saurik just announced on Twitter that Corona has been updated to version 1.0-7 to fix those issues mentioned above…
Saurik noted that this fix is valid for every jailbroken device on iOS 5.0.1, except for iPhone 3GS old bootrom.
If you’ve already installed Corona, simply open up Cydia and update to the latest version. If you haven’t jailbroken your device yet, we recommend you use RedSn0w, which will provide you with a one-stop untether jailbreak.
As usual, make sure to read your jailbreak page for answers to all your questions about jailbreaking.
