iPhone 1.1.3 Jailbreak for Macs released — how to make it work
Posted 24 January 2008 @ 9pm in News, Guides/How-Tos
Hot on the heels of a contentious jailbreak (allowing the installation of unofficial third-party applications on the iPhone) for Windows, Nate True has released a similar jailbreak method for Macs. The Mac method is ostensibly easier than the Windows method, requiring the download and use of a single file dubbed 1.1.3 package maker.
However, there is an important trick for making this file work — once you download it and mount this disk image, move both the file “Run_This” and the folder “data” to the root level of your startup drive, then launch “Run_This.” Otherwise you may receive errors.
Like the Windows method, you will need to downgrade your iPhone to software/firmware version 1.1.1 or 1.1.2 before running this procedure if your phone already has 1.1.3. Downgrading may require that you use a version of iTunes older than 7.6.
To downgrade to iTunes 7.5 follow these steps:
Delete the following files:
- The iTunes 7.6 application (located in /Applications)
- com.apple.iTunes.plist (from ~/Library/Preferences)
- iTunes.pkg (from /Library/Receipts)
- iTunesX.pkg (from /Library/Receipts)
Download and install iTunes 7.5
You can then follow the instructions here to downgrade your iPhone.
We’re still on a more robust, less problem prone jailbreak due from the iPhone Dev team. Use Nate True’s method at your own risk.

This method worked great on my jailbroken unlocked iPhone 1.1.2. I just ran the “Run_This” file directly from the mounted image. My iPhoneSimFree unlocked iPhone is running iPhone 1.1.3 perfectly and phone calls work great. All third party apps disappeared though, and only a uninstall and subsequent reinstall brought them back (updating apps worked too). This was the smoothest update and jailbreak I’ve used. Nice work Nate True!

Why not just wait for the SDK?

Because Apple will control every app made with the SDK… does anybody know wheter anysim works after the jailbreak? I heard that not all apps work after the 1.1.3 jailbreak.

mike3k_dotmac - the SDK doesn’t have a release date yet, so it could be a long wait, also the SDK will not give filesytem access like the Jailbreak does. Being able to personalise your iPod or iPhone is something quite important to lots of people - without this ability you’ve just spent a lot of money on an mp3 player, with the ability it’s much more of a PDA / palmtop computer.

Tried this with OOB 1.1.2 and it made it to:
Done! Now head to Installer.app and install the “1.1.3 soft upgrade” package.
and it never reboots and there is no Installer.app. I waited 30 min and rebooted the phone. It is still 1.1.2.
Did the 1.1.2 need to be jailbroken before I started?
