Corona

Corona is a Cydia package from the Chronic Dev Team on Saurik's repo. It uses pod2g's racoon string format overflow exploit and an HFS heap overflow to untether iOS 5.0.1 on previously-jailbroken devices. Alternatively, users can also re-run the iPhone Dev Team's redsn0w 0.9.10 to untether their jailbreak with the same exploit. The name is an anagram of the aforementioned racoon software.

Changelog

 * 1.0-3 was updated by Saurik to enable redsn0w 0.9.10 users to update the jailbreak through Cydia.
 * 1.0-2 fixes a bug that caused launchctl to not start daemons on-demand.
 * 1.0-1 is the initial release of the jailbreak.
