iPhone 1.1.3 Jailbreak for Macs released -- how to make it work

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.
