Take a look at the video from RedmondPie of the Chronic Dev-Team announcing Absinthe 2.0 at HITB:
For those who didn’t follow the conference, or get caught up in the excitement that surrounded it, the ‘one more thing’ bomb-shell was related to the fact that the Dream Team used their presence at the security event to officially introduce the world to the v2.0 release of their one-click Absinthe jailbreak solution. After months of hard work and exploit finding, mixed with weeks of will-they-won’t-they speculation, it turns out that they indeed did introduce us to Absinthe 2.0.
Our instructions how to jailbreak your device using Absinthe are available here.
InteVyDis has released an untethered jailbreak for A4 devices on iOS 5.1.1 as part of Vulndisco Mobile 1.7. The module is vd_ios_untether_5_1_1. It works by creating a custom bundle you have to install via RedSn0w. Evgeny Legerov posted in twitter:
vulndisco mobile 1.7 is out with untethered 5.1.1
This jailbreak is not free and costs big money. It works only on A4 devices -- iPhone 3GS, iPhone 4, iPad 1, iPod Touch 3G and iPod Touch 4G. It is not yet tested by other hackers. So this might be fake. However famous hacker I01nc notes that the company is a legit source of exploits:
@legerov runs a company: Intevydis that sell exploit packs for many years. If that JB were fake he would hurt his own business.
The unfortunate thing is that now two sets of exploits may be revealed to Apple and some people may pay for the expensive exploit pack despite it being available free in a few days from pod2g.
the most troublesome part is that (potentially) close to 2x as many exploits will be burned now with 2 A4 JBs.
We recommend that you wait the extra day or two for a free jailbreak from pod2g that should work on all devices.
