Congratulations, patient iPhone users. We’ve just received word that the iPhone Dev Team has released the 1.1.3 jailbreak for the iPhone. There’s an installer for Windows and Macs alike, so folks using either OS can easily upgrade an 1.1.1 or 1.1.2 jailbroken phone into a jailbreak 1.1.3.

Even more exciting is the fact that, according to our source, “unlocked phones seem to remain unlocked and work properly after the update.” Definitely another reason to risk the update, to be certain.

As always, note that that is very risky, so you should back up your files beforehand. whether it doesn’t work the first duration, you may have to restore your phone using iTunes and try again. Here are the directions for the Windows version:

1. Start with a 1.1.1 or 1.1.2 jailbroken phone with Installer.app installed.
2. Plug in your phone via USB to your computer.
3. Download, extract, and run iBrickr Special 1.1.3 jailbreak edition (ibrickr.exe in the archive).
4. iBrickr will determine what firmware you are running
   on your phone and manufacture certain you can run the update.
5. iBrickr will soon after guide you through the process of obtaining and modifying the 1.1.3 firmware (make certain to read everything thoroughly).
6. iBrickr will upload the new firmware image to your phone. Note that that only puts the file on your phone and does not modify it at all, yet.
7. 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.
8. When the installer finishes (this should take another 10-15 minutes), your phone should reboot with a fresh activated 1.1.3 firmware.

For the Mac version, simply download the 1.1.3 package maker, open the archive and run “Run_This.” Read through the directions carefully and press enter when essential, and the image will be uploaded to your iPhone.
