Well, the iPhone Dev Team has done it again. A working jailbreak for 1.1.3 is finally here.
STATEMENT OF RISK
As all upgrades are risky, this one is doubly so. You may have to restore your phone using iTunes and start again if it fails. Make sure to back up first!
Let’s continue
This jailbreak, like the 1.1.2 jailbreak, comes as an upgrade. This means you need to have a 1.1.1 or 1.1.2 jailbroken phone already, before you can begin.
Update – unlocked phones appear to remain unlocked and work properly after the update, according to scattered reports.
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.
I’ll be posting a video tutorial on Gear Live’s Bleeding Edge real soon, so watch for that!
If you feel like giving, please donate to a worthy charity. Donations directly to the Dev Team are not possible. If you wish to donate to me directly, you can do that via Paypal.
Props to everyone on the Dev Team, including (in no particular order): netkas, NerveGas, asap18, bgm, Bugout, bushing, chris_, dinopio, drudge, Fred_, gray, MuscleNerd, natetrue, pr3d4t0r, roxfan, Turbo, Zf[strike], np101137, pumpkin, and kroo, along with many contributors who wish to remain anonymous.
And props to Fred_ and planetbeing, who were among the first with a 1.1.3 jailbroken iphone, and Zibri, by whom this method was largely developed. Additionally to Shaun Erickson, who packaged the Installer half of the upgrade, and runs most of the application packaging for the iPhone. He’s looking for a job too – hire him!
Additionally, members of the iPhone Elite team also played a part.

Now you may be wondering how this jailbreak works. Here’s a breakdown:
- iBrickr grabs the 1.1.3 iPhone firmware image and extracts, decrypts, and decompresses the disk image.
- Then it applies a patch, jailbreaking the disk image and activating it, and also installing Installer.app.
- It uploads this new modified image to the phone, as 113_upgrade_image.bin.
- The “1.1.3 soft upgrade” app flashes the phone with the image and reboots.
- You have a perfect, jailbroken, upgraded 1.1.3 phone, with all your settings and music intact!
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.
