Wie soeben das DevTeam in seinem Blog mitgeteilt hat, ist es in kürze möglich mit „redsn0w“ ein Jailbreak des 3Gs durchzuführen. Dieses ermöglicht ein Sicherheitslücke “24Kpwn” im Bootrom. Dieses wird aber noch etwas Zeit in Anspruch nehmen um Anpassungen vorzunehmen und die Anwendung zu testen. Somit wird dann auch der Unlock via „ultrasn0w“ des 3Gs möglich, was das DevTeam bestätigte.

About 5 hours ago (Thursday evening, less than a week after the 3GS launch), we were able to verify that the 24Kpwn exploit that the hybrid team used on the iPod Touch 2G is still present in the bootrom of the iPhone 3GS. That means we can apply the same sort of technique used by our current redsn0w tool to jailbreak and unlock the iPhone 3GS. 

This is great news, but how did it happen?  Why didn’t Apple fix this in their normal cat&mouse fashion?  Well it seems this bootrom was cut in about the August 2008 timeframe, so the unintended early reveal of 24Kpwn earlier this year didn’t affect the iPhone 3GS.

For our technical notes on where the 24Kpwn exploit is in the 3GS, see here (pastebin hash of it is here).    Our original blog post for when this exploit was first found is here.
