Jailbreak
As of July 6, 2011, all variants of the iPad 2 running iOS 4.3.3 have been successfully jailbroken by comex, using JailbreakMe 3.0 "Saffron" which is a userland jailbreak. Apple released iOS 4.3.4 to address the exploited vulnerabilities 10 days after Saffron's public debut.
As of January 20, 2012, all variants of the iPad 2 running iOS 5.0.1 have been successfully jailbroken, using Absinthe which is a userland jailbreak using a modified version of the Corona exploit used in other iOS 5 jailbreaks. On May 25, 2012, all models except for the iPad 2 Wi-Fi (R2) model are jailbreakable on iOS 5.1.1 with Absinthe 2.0, based on Rocky Racoon and the original Absinthe's exploits.
