Two bootrom exploits, two jailbreak solutions; only one can survive

Today was supposed to be the big day for GeenPois0n, an iOS 4.1 jailbreak tool based on the SHAtter exploit. However, Geohot dropped in to steal the show yesterday with the release of his own Limera1n tool.

The problem comes from the fact that Geohot's Limera1n tool uses a different bottom exploit than the one that was supposed to be released today based the work of the Chronic Dev Team and the iPhone Dev Team. Since Apple likely wouldn't release a new hardware revision for current generation devices to block the bootrom exploit, it would be useable until Apple releases its next generation iOS devices.

Instead of releasing two separate bootrom exploits in short succession, giving Apple the opportunity to kill both of them at once when the latest crop of iOS devices are released, the Chronic Dev Team has made the decision to delay its SHAtter-based exploit and instead release a new tool based on Geohot's implementation according to Redmond Pie.

The Chronic Dev Team states:

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.

The Chronic Dev Team seems especially peeved that Geohot's Limera1n is simply a beta release and has plenty of bugs in it, and that it was seemingly released a day before GreenPois0n just to steal the spotlight. In addition, Geohot's jailbreak only works on Windows-based machines -- for now.

But the good news is that a jailbreak solution for the iPhone 4 and iPod touch 4G is now available, albeit in less than optimum form. If you want to take your chances and use Geohot's solution, you can grab it here (Windows-only). However, it may be a safer bet until GreenPois0n is updated to take advantage of Geohot's exploit.

Well, I can tell you limera1n worked on my 3GS, 4.1 unit just fine.

I am a nobody in all of this, but I find it odd and amusing that geohot is taking so much heat over this. In my opinion, unjustly. He did say he would release it on the 1 year anniversary of blackra1n, and he did. It does work as advertised, and it tool less than 30 seconds to do.

I find it odd that the other product is constantly being delayed, and when geohot delivers, half of the community comes down on him.

I can't comment on the ethical or moral aspects of geohot's actions, but personally I'm wondering what does greenpoison have that limera1n doesn't have... They both jailbreak iOS 4.1, they are both untethered, and geohot is going to be fixing bugs while Chronic Dev is rushing to use his exploit...

I agree, Blackra1n was supposedly buggy at first. I'm still using it because I find backups to be tedious and haven't had problems on 3GS.

I think they're just mad they're not in the "limelight". Generally when something is buggy, it is because it requires some sort of special special install (like tethered installation). However, there was a supposed speed/performance increase in the bug fixes of blackra1n.

I think Chronic Dev Team is wise in not releasing another hole, for a just-in-case scenario. If they really want George to not do this, they should do something to bring him aboard. Otherwise, work quicker for the fame.

Besides, with all the greenpois0n trojans/viruses now floating around (possible Apple employees creating havok?), the team should consider a rename.
