Geohot released his jailbreak for iOS 4.1 a few days ago. It’s in beta, so if you’re feeling adventurous or aren’t scared of beta software, then visit limera1n.com.
It’s not a one-click jailbreak like blackra1n was, but it still get’s it done (more or less). It is slightly buggy, but I managed to get it to work.
Unfortunately, this jailbreak did not come without it’s drama. Hit the jump for the full story.
I’m sure at this point we all know about SHAtter: the famed low level bootrom exploit found in the latest iDevices that can allegedly jailbreak the device for good. In other words, this cannot be patched with a software upgrade from Apple. They would have to ship a new crop of devices to fix this.
The Chronic Dev Team has been working this exploit into a their greenpois0n jailbreak for quite a while now, and they recently announced their release date: 10-10-10 at 10:10:10 AM. However, on the night before said date, the infamous George Holtz (aka Geohot) came out of nowhere and put out his beta (read: buggy) jailbreak limera1n, which is based on a different bootrom exploit, but is still one that cannot be patched via software update.
Geohot, who claimed to be leaving the jailbreak scene altogether back in July, has surprised everyone with this, but especially the iPhone and Chronic Dev Teams. While the exploit has been confirmed as legitimate (and in some cases better), it has completely thrown off plans for greenpois0n. As a result, the SHAtter exploit has been delayed. From the iPhone Dev Team’s blog:
Releasing SHAtter now would be a complete waste of a perfectly good bootrom hole in light of limera1n, and so it can be held until Apple closes limera1n’s hole. While there’s no guarantee that Apple won’t also close SHAtter by then, it provides a ray of hope for devices after Apple’s bootrom respin. Meanwhile, look for an alternate implementation of the limera1n exploit in greenpois0n (and possibly other tools), where it should undergo more testing too.
In addition, the Chronic Dev Team had this to say:
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.
Geohot, in his defense, claimed that he released limera1n prior to greenpois0n because he knew that SHAtter would be useful for future devices and that the Dev Teams wouldn’t risk putting 2 exploits out for Apple to fix at once. If Apple patches Geohot’s hole, which supports older devices in addition to the latest, the SHAtter hole might still be open for newly manufactured devices with new bootroms.
Although Geohot’s methodology wasn’t the best, it may show a benefit in the long run.
