6.1.1 beta (10B311) does not fix the jailbreak. It’ll probably happen in a future revision. Don’t upgrade though, evasi0n won’t let you jb.
At least not yet anyway. Remember, this is just beta 1 of what will likely be 3 or 4 developer releases. But for the time being, pod2g says that 6.1.1 does not fix any of the jailbreak’s security holes.
