We had reported that iPhone hacker pod2g of the Chronic Dev Team had discovered a bootrom exploit that could help in jailbreaking iOS 4.1. We have more details about the exploit.
The exploit that pod2g has discovered is the first exploit of the S5L8930 chip, Apple’s A4 chip, which is used in iPhone 4, iPad and iPod Touch 4G.
The bootrom exploit allows the use of unsigned code execution, which could help in creating a tethered jailbreak called SHAtter, a jailbreak for life.
It looks like the same exploit was discovered by Geohot who had abandoned the iPhone hacking community couple of months back.
Since the exploit was discovered on Apple’s A4 chip running iOS 4.1, the tethered jailbreak should work with the current and older iOS devices. Tethered means that the jailbreak needs to be reapplied every time you power down your iOS device. If you let the battery run out or restart your iPod touch then you will need to reapply the jailbreak by connecting to your computer (tethering).
As we’ve explained in our earlier post, a bootrom exploit is a low level exploit that can’t be fixed by Apple with a software update like it did with iOS 4.0.2 to patch the security hole used by JailbreakMe.
Apple can prevent jailbreaking by releasing devices with a new bootrom that patches the exploit, but Apple won’t be able to stop users from jailbreaking devices with the older bootrom.
The iPhone Dev team and Chronic Dev team are currently working hard to bring the jailbreaking tools to users but it is expected to take sometime.
We’ll let you know as soon as we’ve any further updates. So stay tuned here at iPhone Hacks or follow us on Twitter or subscribe to our RSS feed.

Teathered? interesting.
that actually sounds sucky i hope they find a way for an untethered jailbreak as well, but tethered will be ok for the mean time
Tethered? Then they should call it 'Shitter' instead.
Oh there may still likely be an unteathered break, but what's important about this one is that you will always be able to do it on the device you have now, no matter what version apple puts up. So no waiting for new jailbreak when a new version comes out.
Wow, junkkkkk!!!!!!
Way to go Dev and chronic Team! You guys rock.
i thought that bootromexploits are untethered becacause you can change the boot logo and recovery logo?
I was wondering when the complaining would start?
Not very long for you Fags to come out of the woodwork!!
enjoying my 4.0.1 unlocked iphone 4 while waiting jailbreak….
enjoying my unlocked iphone 4 on 4.0.1 while waiting jailbreak for 4.1
dont release a jailbreak because nobody wants it???????
yea i know thats the part i like about it, have only rebooted my iphone4 once since i had it and i only did it then to see how long it took to boot up compared to my old 3G
hey dev guys, keep up the good work and please take your time to build a jailbreaking tool that is stable and easy to use. Godspeed….!!
Geohot is gay the end
Thay, that's unnethethary!! Iths Gayths!!!
Thanks pod2g! Much appreciated. Just don't do the Geohot shuffle. We need you man!
Teathered.. Kind of a downer, i work all day nd by the end of the day my iPhone 4 is dead so re jailbreaking it everytime that's kind of a bummer still kool it can be jailbroken but untethered is the way to go
Tethered wouldnt be so bad if you didnt have to renistall EVERYTHING you had. But i guess it will do. I will wait for a regular JB. Thanks for the hard work.
Tethered jailbreak? Sounds VERY inconvenient…would I have to reinstall and reconfigure my JB apps and plugins every time as well?
I'm a huge JB fan, and I appreciate all the hard work the Devs put in for our collective benefit, but this sounds lousy.
no, your ipod/iphone would just not boot unless you had a computer handy. once you just kicked it on then it would be just fine
it is however very inconvenient, and i am so happy the comex jailbreakme thing is untethered
Umm… you never had to reinstall everything you had. You just had to plug your phone in, and run blackrain.
Who cares if it is tethered? am I only speaking for myself when I say I NEVER turn off my phone…sheesh. thanks guys….i'm as happy as a clam
you obviously don't fly much. For business travelers, it could be a little inconvenient. But its better than nothing.
One concern is when springboard crashes? Or upgrading of cydia items requires respring or reboot I guess that's why lots are worried about it?
i got tierd of this cat and mouse and game and went with a droid x..and am very happy i did..screw apple..for not letting us use our phone to its full capabilities.
Tethered? Maybe untethered would be better for unlockers? As everytime the jailbreak is gone, i can't use the current carrier and itunes locked my device. But still, thanks.
I'm happy the JB will work on my iPad, but any JB for my iPhone 3GS?
Thanks for the great work Pod2g has put in to make this JB possible!
I don't like to being tethered..
You guys are crybaby assholes. Yes it's tethered. But right now there's no other option. If you can't live with that then don't use this jailbreak. Wait for another jailbreak to come out that doesn't need to be tethered.
And tethered doesn't mean you'll lose apps/settings/etc. All that mean is that if you reboot your phone (not respring, but reboot) you'll have to hook up to a computer to allow it to continue the boot process.
Additionally, since tethering requires a computer when you reboot it is inconvenient. But it's the price you have to pay. Reboots don't happen often. Yes, if you run out of battery or turn the phone off on an airplane, then that sucks. But for people with chargers and people who know what airplane mode is it's not an issue. Also, don't install apps that require a reboot unless you're near a computer. You know, WAIT to do that.
This is awesome news for people like me. I had my 3GS jailbroke on 3.1.3 but had to get a warranty replacement and lost the ability to jailbreak (since Apple gave me a replacement with 4.0.2 on it). I miss all the configurations and settings jailbreak gives me (and no, the Apple "multitasking" isn't near the same). I want to thank the Chronic Dev Team and all other jailbreak hackers for their hard work. These folks do this for FREE. We don't pay them for their work. We should be thanking these guys instead of being complete jerkoffs towards them.
Show some goddamned respect you guys.
How will this affect the ability to unblock your phone?
I currently live in spain but will be moving within a week to USA and want to take my iphone 4 but not sure it will be much used if its gonna be such a hassel to unblock it.
Brian man,
Use PKG Backup from Cydia (who have recently took over Rock as well). It should prevent you from having to reinstall everything! PKG is not free, however.
Hey guys im from Cambodia.. Well I hope this tethered jailbreak will hacktivate the phone to homescreen.. I'm so sick of my iPhone 4 that need the ssn and billing zip code from the original owner.. I bought it like 2 months ago.. And now the phone is still stuck at slide for emergency screen the whole time. Anyone is on the same boat as me?
Ordinary_guyz@yahoo.com
Well said buddy..,
What's the big deal with Shatter? Ok Apple would have to do hardware mods to fix it. But for the user it's an arse, I'd shout about a new userland jailbreak frankly, untethered And bloody easy to install
in fact, these days I'm not missing a jailbreak as much as i used too..
if you dont want, dont read this article stupid asshole
you need the at&t micro sim , or used a phonebook sim
Hey , I have I iPhone 3GS 4.0.2 is any way I can jailbreak it ??
3GS. 4.0.2 ?????? Any news
a business traveler usually brings a laptop or something so it still shouldn't be a problem.
You don't need to sync, reconfigure, or restore the phone, only run the exploit with your phone plugged in to make it boot.
Thanks pod2g! your awesome! plz release the tool soon ;(
something to share, eve it is irrelavant here..
I purchased new iphone 4 from AT&T 20 days back and it was replaced with Apple warranty service twice…Every time I had problems with iphone.
hmm..then I spoke to apple customer relations to give me brand new and about to get the replacement with a brand new iphone 4..not like the one that apple replacec in the store….its brand new and they created separate order for it..
The story behind this is — Customer care guy told me that the phone will be shipped in 5-7 business days…but when I checked the status online, it says OCT 1 (no free case after sept 30)….is apple going to change the hardware to fix the antenna issue….!!!!!!!Interesting….!!
Yeah, well every single one of you guys that wasn't an asshole now is… and everyone that was an asshole is now not. So what do you think of that?
This is the best JailBreak you could have! Lets say you dont want your phone Hacked anymore… Just reset your iphone. Lets say your phone gets BRICKED just reset your Iphone the Jailbreak wont be there anymore so how could apple void your warranty. Ill deal with tethering my iphone…
go kill ur self i will read what i want
some folks on here are saying they have to turn their phone off when they go on a plane???? erm…Airplane mode ring a bell guys. lol
Thts so true.
It is funny how the biggest pussies will post threatening things here.. I am sure who cares is a little puss with a nextel $30 phone. No mater what they say they have after my post we all know who needs to be beaten. LOL By little PUSS who cares.
there is no need to turn it off when you fly. That is BS. Oh the plane will crash. NOT. Get a clue mr frequent flyer.
Well done and thank you to those who are working hard behind the scene to Jail break the new update. Some may not appreciate it or will moan about it but there are many more of us who owe you guys a big thanks. I'm new to the iphone and the scene but if I can find a way to donate, I will do it when I start using your JB. Cheers guys.
i live at 417 kewanna louisville ky come over here and ill show u what a pussy i am i have hade iphone 4 scense day one ihad every iphone u probley dont know what a iphone is like i said go kill ur self so nobody hast to read your post love who cares
