Apple just recently seeded iOS 6.1.1 to developers for testing, and many wondered if the minor software update would patch the new evasi0n untethered jailbreak. Fortunately, the answer is no. iOS hacker pod2g recently tweeted that iOS 6.1.1 beta does not fix the jailbreak, although he still recommends that users stay away from the update if they plan on jailbreaking. The evasi0n jailbreaking tool has not yet been updated to support iOS 6.1.1.
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.
