Breaking News: Simpler method to JailBreak & Unlock iPhone firmware 1.1.3 Released

Zibri who was the member of the iPhone Dev Team not so long ago and was alienated for releasing the “true” jailbreak method that the iPhone dev team was attempting to keep secret until the release of Apple’s official SDK has just released a much simpler and what seems to be a single step method to jailbreak iPhone Firmware 1.1.3 along with some minor fixes.

Zibri was also the iPhone hacker to confirm the rumor/news that the iPhone Application SDK Key has leaked.

More details on the latest iPhone jailbreak method available after the jump.
If you are new to the iPhone hacking world then jailbreaking provides read orwrite iPhone filesystem access, allowing installation of unofficial third-party iPhone applications.

Disclaimer: Before I go into the details it is important to mention that before you jailbreak your iPhone, be sure to backup in iTunes so you can restore your iPhone if something goes terribly wrong and since I have not tried this method I am not in a position to confirm either way so do remember that hacking your iPhone is completely at your own risk.

It is also important to note here that though users have got this to work there are some users who are still experiencing problems jailbreaking with this method.

Here are the instructions on how to use this simpler method to jailbreak iPhone firmware 1.1.3 courtesy iPhone Atlas:

Mac users:

Download the "ziphone" file from this link.

Downgrade to iTunes 7.4.2 by downloading it from this link.

Then download Pacifist from this link and use Pacifist to open the iTunes package then force an install.

Launch the Terminal (located in /Applications/Utilities)

Drag the file “ziphone” in the first file you downloaded onto the Terminal window then type “-j”; the command should look something like this: /Users/username/Downloads/ZiPhone\ Folder/ZiPhone/ziphone -j.

Then follow the on-screen instructions.

Windows users:

Download the "ziphone" file from this link.

Downgrade to iTunes 7.4.2 by downloading it from this link.

Run “ziphone.exe” from the first file you downloaded.

Then follow the on-screen instructions.

This method also installs the Installer app which means you will be able to use AnySIM to unlock the iPhone to use any SIM.

In case you face any issues and need clarifications, you could checkout the comments on Zibri's blog post here, he has been quite prompt in responding to queries.
