There were some concerns that iOS 6.1.1 beta will fix the hacks used by the evad3rs dev team to prevent users from jailbreaking their iOS device.
It doesn’t look like Apple has fixed the jailbreak at least in the first beta versions of iOS 6.1.1 that was released to developers yesterday. iOS 6.1.1 includes improvements to Maps app for Japan.
pod2g has however jailbreakers to avoid upgrading to it as evasi0n won’t be able to jailbreak until they add support for it, which will only happen when it is released to the public.
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.

evasi0n jailbreak which was released on Monday was the first jailbreak for newer devices like the iPhone 5, 4th generation iPad and iPad mini. It was also the first untethered jailbreak for iOS 6.x. As of yesterday, it has been used to jailbreak more than 4 million iOS devices.
So it looks like the evad3rs dev team is ahead in the cat and mouse game with Apple at least for now.
