Exploit Found In iPhone 3GS BootROM - Jailbreak & Unlock Due Soon

When the iPod Touch 2G was released in 2008, Apple patched up the hardware exploit that made the iPhone 2G and 3G jailbreakable. Some amount of time later the Dev Team was able to find an exploit in the iPod Touch 2G's bootrom that allowed them to again break the chain of trust and load jailbroken firmware on to the device. That exploit, 24Kpwn, was sat on for some time in hope that it would show up in the next iPhone, before someone eventually leaked it out to the public around March.

It looks like the Dev Team's plans worked, because they've finally dumped the iPhone 3GS's bootrom and it's virtually identical to the iPod Touch 2G's bootrom. As a result, the 3GS bootrom has the same flaw and the same basic 24Kpwn exploit can work on the 3GS. Because the software stack and some of the underlying hardware (e.g. the CPU) have changed the exploit can't be completely recycled, but it allows the chain of trust to once again be broken, making a jailbreak possible.

At this point the Dev Team still has some work to do to bypass the other lesser countermeasures in the 3GS, but ultimately they believe a jailbreak is possible, and that the Ultrasn0w unlocker will also work. In effect it looks like the 3GS will be brought up to the 3G's level of jailbreaking and unlocking ability pretty soon.

The full details are on the Dev Team's blog although there's not much else to talk about at this point until they have a safe & working jailbreak.

I saw this earlier and I'm excited to see the end result. I am a little hesitant I want to jailbreak my phone because I'm fairly certain I made my original 3G slower with all the crap I had running on it. 3.0 fixed a lot of stuff though so all I'd really add would be backgrounder and some theming stuff.

Yea.. the jailbreak itself doesn't slow down the phone, but once you start actually installing processes that are running all the time.. the phone slows down dramatically. I would like to have my Intelliscreen, SBSettings and BiteSMS back though. I'll probably give it a go once this is released.

I'll do it as long as it doesn't slow down the 3gs any. Hoping the beefed up hardware will make the additional processes run faster.

I want this for one reason only, and that's backgrounder. I really miss not having it.

Speaking of which, the iPhoneOS 3.0 compatible version was released today. :D
