Limera1n surprise

After a few very dramatic days in the jailbreak community, geohot has come out of nowhere to release limera1n.  It’s a bootrom-level jailbreak that works on the iPhone3GS, iPhone4, iPod touch 3G, iPod touch 4G, the iPad, and (technically) the AppleTV 2G.

DO NOT USE LIMERA1N IF YOU USE THE ULTRASN0W CARRIER UNLOCK — wait for PwnageTool to incorporate the limera1n exploit. This is so that you can avoid updating your baseband and losing the unlock (possibly forever).

Limera1n uses a different exploit than SHAtter, and in fact covers more devices.  Although some may question geohot’s dramatic and competitive style, he obviously does have considerable skill pulling this together in just over a day (although he’s had the underlying exploit for months).  Credit also goes to @comex, who provides the untethered aspect of limera1n via another one of his growing list of kernel hacks.

The release of limera1n has (hopefully!) averted the burning of 2 bootrom holes at once (both his and SHAtter).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.

Limera1n wasn’t tested very thoroughly and does have some issues.  Geohot typically works these out in subsequent (and rapid) releases (there are already 3 beta versions of it as of Saturday night!).  In the meantime, feel free to discuss any problems and their solutions in our comments section.

Geohot has suddenly appeared back on the jailbreak scene with a new bootrom exploit he is calling limera1n.

Geohot posted a picture on www.limera1n.com of four iDevices displaying the limera1n logo.

P0sixninja has since confirmed that it is real:

yes, the news about geohot is true, the day after we release ETA he decides he wants a piece of the #pie

and yes it is a different bootrom exploit, he wants us to use it in GP, but there’s no way we’ll make our ETA if we do

Greenpois0n was scheduled to be released on October 10th, at 10:10:10 GMT.

StealthBravo also tweeted: geohot’s return is no joke. He is back and is going to release limera1n unless someone talks him out of it.

Update:
P0sixninja has said that they will use Geohot’s exploit if they can implement it in time; however, they will not change the release date.

We are not changing our release date. If we can implement @geohots before 10/10 we will use that, otherwise we’re using ours. #roadblocks

Update 2:
MuscleNerd: As dramatic as geohot’s last-minute all-device JB is, still a shame that two bootrom holes will be burned at once.

Here is a quick update on the upcoming Comex’s jailbreak for iPhone 4 and iOS 4 / 4.0.1. It was only yesterday when we informed you all that Comex in an interview said that he is “almost” done with the jailbreak and now he is waiting for Saurik (the creator of Cydia) to complete the last bits which are required for the jailbreak.

You will have to ask Saurik if he’s done with that bootstrap yet. Like I hate to say this because people will be complaining, but it is pretty close to done.

Today, in an image sent to us by one of our reader who wishes to remain anonymous, Saurik seems to be done with the “bootstrap” thing which Comex wanted from him for the jailbreak. This is what he wrote in a Direct Message to a user on Twitter:

I actually gave comex the bootstrap he needed last night. so I am no longer the bottleneck. (The concept of “bottleneck” is very transient.)

So there you go.. If I read that right, we are probably now closer to the release than ever before. It seems like the new jailbreak tool is now going through final release mechanics before it is released to public. Stay tuned, as we will provide you the download links , along with full how-to guides as soon as the new jailbreak is available.
