Geohot releases a DFU Tool

For those of you who remember, last week Geohot had made a website- It was a timer set to reach 0 on Tuesday 12 PM. He lead us to believe that he would release the Jailbreaking tool if the Dev-Team did not release it. However, this was not the case. It was more of a "test/scare" than anything else. Today, Geohot released a tool that allows you to run "whatever you want" at the DFU level- very simliar to what Pwnage 2.0.1 does.

I still can't believe how many people believed yiPhone. It's amazing how a couple lines of javascript(the counter) can piss so many people off. I was just trying to push dev to work a little harder ;-)I have never done the jailbreaks for any previous versions of the phone, what makes you think this one would be different? I also like to think I have more honor than using someone elses exploit before they do. And really, who was the mascot in the picture? Yorro? Once he exists, maybe yiPhone will exist. Also, heres why a certain person claimed the DFU was the key. You could, without any exploits, upload the 114 iBoot(even to the 3g), the 114 kernelcache(ok, this crashes on the 3g), and a hacked ramdisk. But the filesystems don't mount. And even if they did, you'd need a way around sig checking. Here is a little program(with source of course) to run whatever you want at the DFU level; an implementation of the dev pwnage 2.0 exploit. Pass it a binary file, it will start executing at the start of the file(no file formats to deal with). I'll leave it to dev to explain the exploit used.

You can grab that program here if you wish to do testing on your own. Be careful, as not a lot of support is available for this and you may have a hard time getting in touch with Geo for support :)
