Upcoming iOS 4.1 Jailbreak will be accomplished via a new BootROM exploit - Hardware & Software

[img]http://images.intomobile.com/wp-content/uploads/2010/09/musclenerd-twitter-ios-4.1-jailbreak.png[/img] [quote]Dev Team has found an exploit for iOS 4.1 When the iPhone 4 and iOS 4.0 was released, the Dev Team was able to relatively easily develop a browser-based jailbreak using JailbreakMe.com. The jailbreak made use of an vulnerability in the way that Mobile Safari handled PDF documents. Now, just hours after the official iOS 4.1 ipsw was posted to Apple's servers, the Dev Team has discovered a bootrom exploit that will used in the iOS 4.1 jailbreak. The Dev Team's Musclenerd tweeted, "Crazy timing that @pod2g got latest exploit just as 4.1 went public (lots of work left…keep away from 4.1 for now!)." According to Redmond Pie, this exploit won't be something that Apple will be able to patch as quickly as the previous PDF exploit: [i]Also, the best thing about a low-level bootrom exploit is that Apple wont be able to patch it simply by releasing a new firmware update. Instead, it will require Apple to release a revised hardware version of iPhone 4, iPhone 3GS, iPad and the iPod touches with new bootroms in order to patch the bootrom exploit.[/i] This is good news for iPhone 4 users that want the fixes included in the iOS 4.1 update (proximity sensor, Bluetooth connection issues), while at the same time providing access to the wealth of "underground apps" and customizations that can be had with unauthorized app stores like Cydia. You'll just have to be patient as the Dev Team works its magic to complete work on the iOS 4.1 jailbreak.[/quote] Source: [url]http://www.dailytech.com/IOS+41+Jailbreak+to+Come+Via+Bootrom+Exploit/article19576c.htm[/url] "Unpatchable" jailbreak have once again introduced to the iDevice scene :science: ...until Apple releases a new batch of hardware again

Great news!

Anyone with an iPhone 4 with 4.1 see a decrease of butt dialing?

I'm also interested to know for those who have iPhone 4, if the promised battery performance improvements are significantly noticeable.

Could anyone explain what they mean with "unpatchable"? And will this jailbreak work as easily as jailbreakme or RedSn0w?

[QUOTE=Yoces;24703328]Could anyone explain what they mean with "unpatchable"? And will this jailbreak work as easily as jailbreakme or RedSn0w?[/QUOTE] iBoot is permanently written in the CPU, and cannot be changed unless Apple release a new line of iDevices, because it is READ ONLY.

[QUOTE=psp401.com;24702911]Anyone with an iPhone 4 with 4.1 see a decrease of butt dialing?[/QUOTE] Can't really say on that, cause my phones passworded and it's never butt dialed ever, yet, I guess :\ [QUOTE=B1N4RY!;24702957]I'm also interested to know for those who have iPhone 4, if the promised battery performance improvements are significantly noticeable.[/QUOTE] Haven't noticed a difference, I just got the phone not too long ago, it was a huge difference from the previous iPhones, but this update I haven't really noticed much difference.

[QUOTE=B1N4RY!;24703430]iBoot is permanently written in the CPU, and cannot be changed unless Apple release a new line of iDevices, because it is READ ONLY.[/QUOTE] You mean releases a new version of the iBoot firmware. There was a similar exploit found in the 3GS, and they fixed it up about a month after with a new version of the bootloader.

[QUOTE=DogGunn;24703572]You mean releases a new version of the iBoot firmware.

Apple fixed the 24K exploit by releasing a whole new revision of iDevices with a patched bootrom. You can't update it software wise.

[editline]03:10PM[/editline] Oops, forgot to mention that it was an update released on new iPhone 3GS.

Also, iPhone 3GS is not the only device they patched. iPod Touch was also patched, hence the 2nd Gen MC models

A new line? Most people would've thought that means a whole new series of different devices. For instance, Apple just released a new lineup of iDevices last week. [editline]03:14PM[/editline] That's all I was saying.

[QUOTE=B1N4RY!;24702957]I'm also interested to know for those who have iPhone 4, if the promised battery performance improvements are significantly noticeable.[/QUOTE] Yup. My 3G would run out of battery so goddamn fast, I'd end up re-charging it twice a day. I only have to charge my iPhone 4 once every two days. Still seems short I know, but I'm on the thing all day long in school, in transit, etc.

Oh here we fuckin' go.

fuck yeah, i mistakenly upgraded from the jailbreakable 4.0.1

Great! Free jailbreaks for all forever! At least for this device... Oh, and it also works on the iPad. Enjoy.

Fuck yes

[QUOTE=woolio1;24720320]Great! Free jailbreaks for all forever![/QUOTE] Nope. Only until Apple start shipping out the new devices with a patched bootrom

Didn't they make the MC model iPods for that? That's why you can't buy an MB model anymore...

Do i have to re-buy my Ipod touch? I got it before September fyi. And why can't we have 4.1 (I did read it)

Will this support current MC models? I think it should, right?

Oh yeah.

[QUOTE=woolio1;24735894]Didn't they make the MC model iPods for that? That's why you can't buy an MB model anymore...[/QUOTE] Different exploit.

I'm so looking forward to this :)

[QUOTE=UserDerth;24736008]Do i have to re-buy my Ipod touch? I got it before September fyi. And why can't we have 4.1 (I did read it)[/QUOTE] lol you didnt get it, for apple to patch the exploit, they need to change the hardware.

The Jailbreak is going to be called SHAter!

So why did they say to stay away from 4.1? are they just saying that to people who already jailbroke? Or to tell people to not upgrade to 4.1 because it does something else?

Stay away from it intill the new jailbreak comes out
