A Working Jailbreak for the 1.1.3 firmware is here but comes with a RISK! As all upgrades are risky, this one is doubly so. You may have to restore your iPhone using iTunes and start again if it fails. Make sure to backup first!
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 iPhone already, before you begin. 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.
– 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.
