Corona

Corona is a package on Saurik's Cydia repo that uses pod2g's Racoon string format overflow exploit and a filesystem overflow to untether iOS 5.0.1 on A4 devices, right on an already tethered jailbroken device without a computer. Devices that aren't jailbroken should use redsn0w 0.9.10 to install the untether.

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 is the initial release of the jailbreak.
