The new bootrom exploit now has a name. It’s called SHAtter. It’s a low-level exploit found in the bootrom section of all current iOS devices.
Yes, that includes the iPhone 4, iPad, and the new 4G iPod Touch. That’s great news, but the sad bit is it might be tethered unlike JailbreakMe which is a userland jailbreak that you can perform anywhere at anytime. It’s not that convenient to use, but on the good side, it won’t be that easy for Apple to patch as well. Apple will have to make hardware revisions in order to plug this new hole.
iOS firmware updates won’t be enough to patch this exploit. There’s still no new info yet as to when this SHAtter iOS 4.1 jailbreak will be released, but we do know that both the Chronic Dev Team and iPhone Dev Team are already hard at work in developing a tool to hack iOS 4.1 wide open.
That’s about it for now, but rest assured, we’ll be talking more about this SHAtter iOS jailbreak once new info becomes available.
If you either have a new iPhone 4 with iOS 4.0.2 pre-installed by default or upgraded to the new firmware without saving your SHSH blobs first, here’s a trick that might allow you to downgrade to iOS 4.0.1 thus allowing you to jailbreak your iPhone via the JailbreakMe website. Emphasis on the word might as this hasn’t been confirmed to work as promised.
In a nutshell, you just have to slightly modify the official iOS 4.0.1 ipsw file, and then transfer all the contents to the iOS 4.0.2 ipsw file. This will allow you to fool your iPhone 4 and iTunes into believing that it’s installing iOS 4.0.2 while the truth is its iOS 4.0.1. Theoretically, it sounds plausible, but as we all know, plausible is not a guarantee that it’ll work.
For the full instructions on how to go about it, you can find it by going to Redmondpie’s site.
Apple has released iOS 4.0.2 for the iPhone 4, iPhone 3G/S, iPod Touch, and iOS 3.2.2 for the iPad which, as promised, comes with the necessary fix to plug the jailbreakme PDF exploit we mentioned a while back.
JailbreakMe 2.0 Star is the userland jailbreak for iPhone 4, iPhone 3GS, 3G on iOS 4 / 4.0.1, iPod touch on iOS 4, and iPad on iOS 3.2.1 is out. It is a browser based jailbreak, all you have to do is to browse to www.jailbreakme.com from your iOS device to jailbreak it.
