So far we have seen a couple of ways to JailBreak iPhone firmware v1.1.2, however the process has been somewhat complicated.

Folks at iPhone Atlas have posted a method, which they claim is somewhat easier to JailBreak iPhone firmware v1.1.2 which will work on Windows and Mac thanks to the work carried out by the iPhone Elite dev team.

The process apparently also does not require any third-party utilities other than what is included in the package from Conceited Software.

Links and more details to JailBreak iPhone firmware v1.1.2 available after the jump.

Before you go through the process, do note that though folks at iPhone Atlas claim that the method is simpler, however they do highlight that the process is still somewhat complicated. It is also quite lenghty as it is a 23-steps process.

So if you have iPhone running on firmware v1.1.1 then I would recommend that you stick with it for now.

This method is essentially for all those who have bought a new iPhone with firmware v1.1.2 or accidentally upgraded their virgin iPhone to the latest version of iPhone firmware and would like to install native third-party iPhone applications.

I have not tried this out to confirm whether it works or not, so if you are planning to check this out remember you will be doing so at your own risk. You need to also ensure that you have access to Wi-Fi connection on your iPhone to try it out:

Please find below the 23-steps to JailBreak iPhone v1.1.2 courtesy iPhone Atlas:

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. Put iPhone in recovery mode (hold the sleep and home [on the top of
   the iPhone] buttons simultaneously until the screen goes blank, then
   release the sleep button but keep holding the home button until a
   screen showing an iTunes icon and a USB cable appears).
3. Launch iTunes if it isn’t open. You will receive a message that says “iTunes has detected an iPhone in recovery mode”
4. Do not restore the iPhone at this point
5. 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. You’ll receive
   the error message “1015? indicating a failure to restore — this is
   normal.
6. Download the iTunes 1.1.2 jailbreak folder from Conceited Software.
7. If you are using a Mac, double-click jailbreak.jar in the file you just downloaded. If you are on a Windows system, double-click the file windows.bat. Click the “Boot from Recovery” button. This should force the iPhone out of recovery mode.
8. This process can take several minutes. In our case, the progress
   bar never finished, but the proper process occurred — if it works, your
   iPhone screen will go completely black and the device will power off.
   At this point, you should hold down the power buttonfor several
   seconds until the device restarts. If 10 or minutes have gone by and
   nothing has happened (the recovery mode screen, with an iTunes icon and
   a USB cable, is still displayed on your iPhone), try disconnecting your
   iPhone and reconnecting it and trying again.
9. You will no see the “Waiting for Activation” screen, but your iPhone won’t activate.
10. Slide to unlock your iPhone, and launch Safari.
11. Navigate to www.jailbreakme.com.
12. Go to the bottom of the page and tap “Install AppSnapp.”
13. You will see the “Downloading Programs” message and a spinning progress indicator.
14. 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.
15. Slide to unlock your iPhone. You will see the “Installer” icon on your home screen. Tap it.
16. Tap “Install” at the bottom of the screen, then tap “Tweaks 1.1.1?
17. Scroll down to a package called “OktoPrep” and tap it, then tap the “Install” button in the upper-right corner.
18. 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.
19. 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 (not Restore). Your iPhone should receive the 1.1.2 update, and eventually activate in iTunes.
20. [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.]
21. After the installation of firmware 1.1.2, Installer will vanish from your iPhone — this is normal.
22. Go back to the folder you downloaded from Conceited Software and again run the jailbreak.jar file on a Mac or the windows.bat
    file on a Windows system. This time, check the “Install SSH option”
    then press the “Jailbreak” button. This process takes several minutes —
    do not perform any other operations on your iPhone during this process.
    
23. Your iPhone will reboot several times. When you’re done, the
    Installer application should now be on your screen and the iPhone
    should properly activate. Consult our Applications page for information
    on using Installer.
