Foolproof (or close to it) iPhone 1.1.2 jailbreak

Jailbreaking (allowing for unofficial third-party application installation) iPhones that have been updated to firmware/software revision 1.1.2 is an arduous process. It’s cumbersome, fraught with pitfalls, and inconsistently successful. In fact, given the questionable value of firwmare/software update 1.1.2, we’d recommending sticking with version 1.1.1 if you’d like to use third-party applications on your iPhone. However, if you’ve already updated to 1.1.2, there’s not an easy way to go back to version 1.1.1 an keep your phone active for voice services. As such, we’ve put together what we think is the most error-proof process for accomplishing a jailbreak on 1.1.2 iPhones, taking into account the problems most readers have had with initially published processes.

This guide assumes that you are running iTunes 7.5. There is no need to downgrade to a previous version of iTunes for this process.

1. Download the iPhone 1.1.1 firmware/software package, and after it is downloaded, make sure it still has the extension .ipsw and not .zip. Rename it if necessary (the correct name is iPhone1,1_1.1.1_3A109a_Restore.ipsw).
2. In iTunes, select your iPhone from the left-hand pane (source list) and click the “Summary” tab. Hold down the option key, then click “Restore.” Select the 1.1.1 package you just downloaded.
3. Allow the process to complete, after which you will receive an “Error 1015″ message, and an inoperable iPhone — this is normal. Do not attempt to restore the iPhone with iTunes or perform any other procedures.
4. Download iNdependence 1.3 beta 2 disk image.
5. Move the application iNDependence (it has an icon depicting Napoleon Bonaparte riding an iPhone) off its disk image into your Applications folder (otherwise you will get an error message in following steps).
6. Download MobileDeviceFramework 7.4.2.
7. Rename MobileDevice_7_4_2.framework to MobileDevice.h (press OK when the Finder asks if you are sure you want to do this).
8. Launch the application “iNdependence MobDev Tool” that was included on the iNdependence disk image. You should see the following message.
9. Select the folder MobileDevice.h (which you just renamed) using and click Open. At this point, you will be presented with what looks like the same “Open” dialog box, and you might think the operation has failed — it hasn’t. You are now being prompted t select the iNdependence application. Notice that the text at the top has changed to “Choose iNdependence.”
10. Launch iNdependence from your Applications folder
11. You will most likely see a message that states “Disconnected: Waiting for iPhone” and a spinning progress wheel. At this point you should disconnect your iPhone from your computer then reconnect it.
12. Your iPhone should display the “Activate iPhone” screen, and the status message in iNdependence (after a few seconds) will state: “Connected to iPhone - Firmware 1.1.1 - not activated …”
13. Launch iTunes if it is not open. It will prompt you to activate your phone, which you should do. However, you will see the message “Waiting for Activation” forever.
14. Slide to unlock your iPhone, and launch Safari.
15. Navigate to www.jailbreakme.com.
16. Go to the bottom of the page and tap “Install AppSnapp.”
17. You will see the “Downloading Programs” message and a spinning progress indicator.
18. At the end of the process, your iPhone will be jailbroken under firmware version 1.1.1, but you won’t have access to voice services yet.
19. You will see the “Installer” icon on your home screen. Tap it.
20. Tap “Install” at the bottom of the screen, then tap “Tweaks”
21. Scroll down to a package called “OktoPrep” and tap it, then tap the “Install” button in the upper-right corner.
22. In iTunes, select your iPhone from the source lift on the left-hand side. If it prompts you to restore your iPhone from backup, you can do so (by pressing the “Continue” button), after which your iPhone will reboot and again try (and fail) to activate.
23. With your iPhone selected on the left-hand pane, click the “Summary” button a the top of the window. You will see a message stating “A newer version of the iPhone software is available (1.1.2). […]” Click the Update button.
24. [At the end of the process, you might see an error message indicating that the iPhone could not be restored because of an “Error 1602″ or similar. If so, follow the instructions in this Knowledge Base article to re-install iTunes. You then, unfortunately, have to start the process all over again.]
25. After the installation of firmware 1.1.2, Installer will vanish from your iPhone — this is normal.
26. Download the iTunes 1.1.2 jailbreak folder from Conceited Software and launch the file titled jailbreak.jar, then follow the on-screen instructions.
27. After you are prompted to restart your phone, the Installer application should now be on your screen and the iPhone should properly activate. Consult our Applications page for information on using Installer.
