Yesterday, Geohot released the Limera1n tool to jailbreak iOS 4.1 on iPhone 3GS and 4, iPod Touch 3G and 4G and iPad on iOS 3.2.2. The Chronic Dev Team had asked Geohot not to release Limera1n now and to save it for future jailbreak. But, as you all know, Limera1n was released to jailbreak iOS 4.1.
This is what Chronic Dev Team have posted in their 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.
For the sake of the jailbreak community, they have decided to save the SHAtter exploit for the future and have thus delayed the release of the GreenPois0n jailbreak tool.
