greenpois0n only works on firmware 4.1, so (only if you have an iPhone 4!) if you are on a lower firmware make sure you use TinyUmbrella to preserve your baseband.

Initially, this will be a Windows-only release. This is due to some technical complications that we soon hope to correct. We apologize for any inconvenience.

Thanks to geohot for the bootrom USB exploit. We have opted to use that instead of SHAtter for the sake of exploit presevation.

This release of greenpois0n supports:
- iPhone 4
- iPhone 3G S
- iPod touch (4th Generation)
- iPod touch (3rd Generation)
- iPad

Soon there will be another release, adding things like support for:
- Apple TV (2nd Generation)
- iPod touch (2nd Generation)

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.

Development on the jailbreak for iOS 4.1 will still continue as planned, and is still in progress. This internal team change will not affect the end user in any way at all.

Thank you for the concern, and your ongoing patience is appreciated.

More information soon to come…

iBSS.n90ap.RELEASE.dfu (4.0.1) Decryption Information
Key: d05c3c40db40e738926f811b8b1314038d26096c4102461698a49098c47a3fe6

Update: Late last night it was verified that the iPad and iPod touch (4th generation) are also vulnerable to our exploit!

Update 2: Some facts…
- We have not yet announced if this is tethered or untethered
- We have not yet announced details about the exploit
- Anything you read saying it is one of the above in definite terms is just speculation, again, we have not given official word about the tether status or any details regarding the exploit used.

Update 3: Just to help cut down on speculation, here is a list of some of our Twitters, any info read on them about the jailbreak will be legitimate:
- AriX
- chronic (informal)
- chronic (formal)
- chronicdevteam
- pod2g
- posixninja
- MuscleNerd
- OPK
- saurik
- semaphore

(might have missed a few, if I did them they will be added later, so be sure to check back if you aren’t already doing so)

Update 4: Although we still can’t give any details of the exploit(s) that need to be used, I figured I’d make an update here to just let you guys know that we are still working hard on the jailbreak and making steady progress. Please keep in mind that even though we have had the method for awhile, there was a certain very key element that we (or rather, pod2g the great) only got working a few days ago, so it’s not like we have this packaged up and we are just sitting on it. It is being actively worked on as I type this (the loader, the payload itself, the easy to use computer-side tools, the payload, the patches, etc.) Just hang tight, it will definitely be worth it.

Update 5: All comments by user “Chronic Dev Sucks” and replies to him have been deleted. We will not tolerate threatening or harassment in the blog comments from either side of the little “debate” that was going on, if you’d call it that.

With the new JailbreakMe.com method of jailbreak released, it seems that some people are already in the process of figuring out how it works. Once the exploitation method is disclosed to the public (it’s related to PDF handling), black hat hackers would be able to easily set up their own websites that load their own malicious PDFs that they crafted to do something like steal your address book or text message database. In a pre-emptive attempt to combat this, BGR has been informed that a plugin named “PDF Loading Warner” has been created, which will hooks into the system and displays a warning before a PDF can be displayed.

If you install this plugin and navigate to a website that should not be showing a PDF and get this warning, then you are able to click “Cancel” and the system will block the PDF from loading and subsequently stealing your data. It should be available from Cydia in the next day or two we hear, or more experienced users can grab the .deb file here and install it manually via SSH or iFile.

A lot of work has went into this. Simply navigate to the following URL on your device’s browser to jailbreak (iOS 4 only, except iOS 3.2.1 on iPad is also supported):

For simplicity, here is a “mirror” of FAQ:

What’s a jailbreak?
A jailbreak is simply the ability to run apps and use themes and tweaks not approved by Apple. Jailbreaking doesn’t slow down your device or use any extra battery. A jailbreak lets your device be how you want it.

How can I be sure that I can always jailbreak in the future?
Firstly, don’t update past 4.0.1, the last firmware JailbreakMe supports. Secondly, and arguably most importantly, allow Cydia to “make your life easier”. This will allow you to always restore back to the latest firmware available when you select that option.

Is JailbreakMe reversible?
Of course! If you ever decide that you want to remove your jailbreak, just connect your device to your computer, sync, and then press Restore in iTunes.

Is it legal in the USA?
Yes. A new DMCA exemption was approved by the Library of Congress, specifically allowing jailbreaking.
