MuscleNerd and the gang have confirmed that those meddling Apple engineers have patched both the SHAtter and Limera1n vulnerabilities in the iPad 2. Other exploits are being worked on, but p0sixninja has tweeted that “the exploit is very complicated, so I’m not positive. But things aren’t looking good. I’m still optimistic though“.
Early testing also seems to show at least one thing SHAtter depends on was gone by March 2010 too
This means any early iPad2 jailbreaks will have to be purely userland
This means that hackers will need to start from scratch and find a brand-new vulnerability in order to jailbreak the iPad 2. An untethered userland jailbreak will likely be released first, possibly followed by an untethered jailbreak sometime in the future.
