Chances that your 1.1.3 iPhone or iPod Touch will be updated and jailbroken within the next seven days are pretty high, thanks to a collaboration between the iPhone Dev team and the iPhone Elite. The 1.1.3 jailbreak firmware is based on a “soft update” exploit, which will merge the files from 1.1.2 and 1.1.3 - allowing you to enjoy the best of both jailbroken worlds. Due to copyright issues, you can’t get the decrypted software itself from the developers. You can, however, perform the upgrade by getting a decryption key from the team and using this to decrypt a disk image in the Apple-supplied ipsw archive (located inside the home library or downloadable from Apple). The team will also give you instructions on how to do the soft upgrade, and might include a tool that will automate this process, just like the jailbreak.jar from the 1.1.2 update. If you haven’t upgraded the firmware to preserve your iPhone unlocks, you can still use the 1.1.3 software though you won’t be able to access the Google Location feature.

Watch out for the release of the 1.1.3 jailbreak sometime “soon”!

UPDATE: The 1.1.3 jailbreak is now available. This is a risky process, so backup, backup IN iTunes. Meh, I wouldn’t do this. Remember that this is an upgrade only, not a clean jailbreak from an AT&T iPhone with 1.1.3 firmware. Your iPhone must already be jailbroken from 1.1.1 or 1.1.2.

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.
