The iPhone Developement Team has published its official jailbreak for 1.1.3 firmware for the iPhone. They said they would and now it’s here. This is a working jailbreak for 1.1.3 but it only works as an upgrade. It will not work for a “married” AT&T iPhone. Your iPhone will need to be a jailbroken 1.1.1 or a jailbroken 1.1.2.

Warning. Jailbreak for 1.1.3 is extremely risky. iPhone Dev Team has theirs working but that doesn’t mean it will work 100% without consequences, especially if you don’t do yours right. You need to back up on iTunes before you begin the process…

Or wait for the video tutorial… Anyway, here it is.

MAC VERSION – Download the 1.1.3 package maker and open it, then run Run_This. Read carefully, press Enter when necessary, and the image will be uploaded to your phone.

Here’s how you do it:
- Start with a 1.1.1 or 1.1.2 jailbroken phone with Installer.app installed.
- Plug in your phone via USB to your computer.
- Download, extract, and run iBrickr Special 1.1.3 jailbreak edition (ibrickr.exe in the archive).
- iBrickr will determine what firmware you are running on your phone and make sure you can run the update.
- iBrickr will then guide you through the process of obtaining and modifying the 1.1.3 firmware (make sure to read everything thoroughly).
- iBrickr will upload the new firmware image to your phone. Note that this only puts the file on your phone and does not modify it at all, yet.
- When iBrickr finishes (should take about 10 minutes), it will tell you to go to Installer and install the “1.1.3 soft upgrade” package. Do that.
- When the installer finishes (this should take another 10-15 minutes), your phone should reboot with a fresh activated 1.1.3 firmware.
