Updated: Greenpois0n jailbreak released! [Jailbreak]


Earlier today, Chronic Dev Team member Joshua Hill (@p0sixninja) announced via twitter that they've released Greenpois0n, a jailbreak tool for the iPhone, iPod Touch and iPad running iOS 4.1. This falls behind their initial goal of pushing the jailbreak out on 10/10/10 at 10:10:10AM due to GeoHot releasing his Limera1n jailbreak first.

Previously based on the SHAtter exploit, Greenpois0n now uses the same bootrom USB exploit that GeoHot implemented in his own release late last week. They decided on using the same exploit as to not give Apple any heads up on how the SHAtter exploit was conducted, in order to ensure that Apple doesn't quickly patch both exploits in a future iOS update.

You can grab Greenpois0n via greenpoison.com, but you may also want to visit their blog before attempting the jailbreak for more info and to make sure your iOS device is supported. As with the Limera1n exploit, this allows for jailbreaking the iPhone 4, iPhone 3GS, iPod Touch (3rd and 4th gen only) and the iPad. Additionally, they've announced that a future update will also include a jailbreak for the Apple TV (2010) and the 2nd generation iPod Touch.

Will you be jailbreaking your iOS device using Greenpois0n? Let us know in the comments!

UPDATED: Seems to be some launch day pains so you may want to hold off using greenpois0n until the initial bugs get worked out. Either way, if you want to talk about it or get help, head on over to our Jailbreak Forum.

Updated: Greenpois0n jailbreak released! [Jailbreak]


Before people ask about unlock, you might want to mention that MuscleNerd Tweeted that an unlock will be coming, but not til 4.2 and it will cover 3GS as well :)

So what will be the difference between greenpo1s0n and limera1n! I'm already jailbroke my phone with limera1n..

Honestly, I think that I'm just going to keep my iPhone 4 at 4.0.1. I'll just wait till November and Jailbreak when they come put with 4.2. Plus, I don't feel like redownloading all those jailbroken apps.

@BBYM No difference really. They work on same iDevices. Only difference is Greenpois0n has version for Mac while Limera1n doesn't (at least not yet).
@EagleyeSmith Do what you want, but I wanted the proxmity sensor fix asap and HDR photos and Game Center are nice too.

There is absolutely no assurance that 4.1 will fix your proximity sensor issues. I know perhaps 5 people that still have problems. 4.1 did nothing for them. HDR photos take forever to load and so the 4.1 update is just not enough reason. Waitin for 4.2. Just my opinion.

"in order to ensure that Apple doesn’t quickly patch both exploits in a future iOS update."
Not true. Since both the SHAtter and limera1n exploits are BootROM exploits, Apple can only fix them with an updated BootROM (which is a hardware change) as they did with the 3GS after a few months of production or which each new iPhone generation had.
The only thing about this exploit that Apple can fix with an iOS update is the part that makes it untethered. The bootrom exploit itself only allows for a tethered exploit, which means you would have to connect the iPhone to a computer every time you turn it on in order to keep the Jailbreak. But comex found a userland (i.e. fixable through an iOS update) exploit to make the bootrom exploit untethered.
But it seems (according to MuscleNerd on Twitter) that comex has found some more exploits to make the bootrom exploit untethered even on future iOS versions.
That means that the near future (until new iPhone model or Bootrom revision) seems covered pretty well by our dear Jailbreakers! :)

In the above article, it mentions iPhone 4, and 3GS....does this jailbreak exclude 3G iPhone?

@Boots Thanks for the heads up. Saw the Mac button and assumed it was live. @bryan guess Mac users gonna have to wait another day or two :(
@Andy Brown - While true I can tell you I've gone from dropping a call or hitting speaker or mute button unintentionally at least twice per day to not one time since going to 4.1.

So is greepois0n already untethered at the bootrom level? Or is that something upcoming in a future jailbreak?

hello there.. i have jailbroken my iphone 4 with greenpois0n and it works fine, and looks great.. thanks to all chronic-dev team members to get gp so fast online.. iam very happy with greenpois0n.. well done..

Lot of people are asking for the comparison between limera1n and greenpois0n jailbreak and which one to be preferred... Also, another question is what if both the jailbreak methods are used.???
I found this post http://blog.onlyonweb.net/post/466 that explains both of these questions along with simple steps on how to use Greenpois0n and Limera1n to jailbreak the iPhone IOS 4.1/4.0.x..
Good luck.

Hey I am trying to jailbreak my iphone 3gs with 4.1 IOS software. I was wondering if green poision will work on MAC it has one for windows but the site doesnt for MAC. If someone could please get back to me that would be great. I obviously have a MAC computer not a windows. My email is nick_lal@ymail.com.
Thanks, Nick

I tried greenpois9n till my fingers hurt still nothing so thanks for nothing but sore fingers and a bad day

Does anyone know of a good way to jailbreak the iPhone 3G on PC? As far as I can tell limera1n and greenpois0n are for 3GS and above... P
