Apple has added a new layer of security for the iPhone 3GS and steps need to be taken to prevent these measures from affecting future jailbreaks.

Apple has added a new layer of security to the iPhone 3GS. I mentioned it several posts earlier; it’s the ECID field. When iTunes starts the restore process, they contact Apple servers to generate signatures just for your device. It’s important you get these signatures for your phone before a new version of the software comes out. I had previously suggested doing this by dumping usb while the iPhone restores. But this is complicated.

Thanks to GeoHot purplera1n.com will help you generate a unique certificate for your phones iBSS. You will need to keep this certificate for possible use in the future.

And so it shall be pwned for life

Earlier today, we got our hands on the bootrom. With the help of chronic, posixninja, and pod2g, I verified that it is still vulnerable to the 24kpwn exploit present in the iPod Touch 2G. This is great news for all of you. Basically, this means if someone makes a tethered jailbreak, it easily becomes untethered, because the boot chain is broken. Expect big things soon

On a personal note, I’m sad. Apple, it took me a week to break through your new defenses. And to let us reuse an exploit like that; 24kpwn was so 5 months ago. Although I imagine it must have been painful watching the devices roll by on the assembly line, knowing they all had a hole in them and you couldn’t fix it.
