Hacker claims he can get signed version of any internal iOS firmware

jailbreak

p0sixninja, iOS Hacker and a member of the Chronic Dev team has made some interesting claims.

He claims that he can “get a copy of any apple internal firmware, aka signed version of ssh of telnet”. While it is not clear how he would manage to get the file, it could have some significant implications for jailbreakers.

Over the last few years, Apple has used a dual strategy of preventing users from jailbreaking their device. It not only releases new iOS software update, which fixes the vulnerabilities used by the jailbreaks, it also stops signing the older iOS firmware file, which prevents users from downgrading back to the older version that can be jailbroken.

So as an example: if you accidentally upgraded to iOS 6.1.4 on your iPhone 5 or iOS 6.1.3 on other iOS devices then there is currently no way to jailbreak your newer iOS devices like the iPhone 5 as iOS 6.1.3 fixes the vulnerabilities used by evasi0n. There is also no way to go back to iOS 6.1.2 and use evasi0n to jailbreak your device as Apple has stopped signing iOS 6.1.2.

If there was a way to get the signed version of the older iOS firmware file then users could downgrade back to an iOS version that can be jailbroken until a jailbreak for the latest version is released. It is quite possible that we have misunderstood his tweets as there are some elements we don’t understand.

It’s not really clear what p0sixninja means by an “apple internal firmware”. It is also not clear what he means by “of ssh of telnet,” but he has published a screenshot of Xcode where Telnet and SSH port on his iPhone running iOS 7 beta with Connect as mobile doesn’t seem standard.

posixninja also claims that he plans to release a lot of amazing things, which is bigger than jailbreak:

It is quite possible that he is just trolling us, but we thought it may be worth covering it for sake of discussion. We’ll keep you posted as soon as we get more details.
