Chronic Dev Team have delayed Greenpois0n jailbreak that was expected to release today. There is no specific ETA for Greenpois0n release now as the Chronic Dev Team say they’ll release it soon as it’s done. Here is excerpt from their official blog:
Thanks to the irresponsible antics of geohot, we will have to delay the release of greenpois0n (new ETA = as soon as possible), so that we have time to clean up his little mess and integrate the exploit he uses in limera1n into greenpois0n. This way, we can save SHAtter for future devices that may still be vulnerable to it.
We know that this is not what some people want to hear, but due to geohot needing to feed his ego (as usual) and revealing his limera1n exploit, we do not have any other responsible options.
