NateTrue has recently leaked a v1.1.3 Jailbreak via iBrickr without the Dev Team's permission. He has been kicked off the Dev Team.
Jon from Zdziarski.com claims that certain unallowed files were included: Against our wishes, he's included both files belonging to Apple and patches which contain copyrighted information by Apple, making his personal release illegal and unethical. .
NateTrue responds on his blog: Regarding the drama about this release - there is identifying information in the patches, that contains pieces of the firmware as markers for what changes should be made to it. None of it is in any sort of useful form until it is merged again with a real 1.1.3 firmware image, which is downloaded directly from Apple.
I have add a tutorial to iClarified on how to perform the recently released jailbreak; however, for those cautious ones it might be best to wait for the official Dev Team release.
