The details page for Corona in Cydia.

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. 

A5 Jailbreak

Main article: Absinthe

According to pod2g's blog, he was having problems with the app sandboxing system used on the A5 processor in the iPad 2 and iPhone 4S, so he got planetbeing, MuscleNerd, Joshua Hill and saurik, dubbed the "dream team", to help to fix it[1][2]. Dustin Howett also demoed the A5 jailbreak on YouTube. It was released on January 20, 2012 as Absinthe.
