Guide to activate & jailbreak the iPhone 1.1.2 OTB on Windows - Prerequisites (1/4)

The initial preparation step (STEP 1) in order to get a free and usable iPhone 1.1.2 OTB (Out of The Box) requires to obtain all the software needed to activate and jailbreak the iPhone. This guide is based on the following components and versions:
  • Computer OS: Windows XP SP2
  • iTunes v7.5.0.20
  • iPhone firmware version 1.1.2 OTB - Serial number: XXX47... (bootloader v4.6)
  • iPhone modem firmware version: 04.02.13_G (aka baseband)
The iPhone firmware version can be easily determined by looking at the default, unactivated, iPhone screen. If it shows a globe (left image), it is version 1.1.1 or lower; if it shows a music CD and cable (right image), it is version 1.1.2.

How to check the iPhone modem firmware version:
1- Turn on your iPhone.
2- The default screen shows the "slide for emergency" button at the bottom.
3- Slide and you will get the "Emergency Call" screen plus the phone keypad.
4- Type the *3001#12345#* number and press the "Call" button.
5- You will get the "Field Test" window.
6- Select the "Versions" menu option.
7- You will get information about your firmware (find the typo :)), such as:
Firware version: 04.02.13_G
LCD Panel ID: ...
This output corresponds to version 1.1.2. The previous iPhone version, 1.1.1, shows 04.01.13_G (01 instead of 02) as the modem firmware version. A complete list of iPhone versions and the corresponding modem firmware versions is available here.

Once the details of the required elements have been verified, you need to download three files:
After downloading these files, verify their integrity using any MD5 tool, like md5deep:
C:\>md5deep iPhone1,1_1.1.1_3A109a_Restore.ipsw
d6508e86d588a76547b9cae52d38e325 C:\iPhone1,1_1.1.1_3A109a_Restore.ipsw
C:\>md5deep ibrickr_v0.91.zip
cff8165f71f74af3f5ad75250fd21d31 C:\ibrickr_v0.91.zip
C:\>md5deep 1.1.2-jailbreak.zip
eaef139f3a14ee9aabc7dc445741ca31 C:\1.1.2-jailbreak.zip
At this point, you are ready to jump to STEP 2 and downgrade the iPhone's firmware version from 1.1.2 to 1.1.1.

Sorry Paresh, but this guide was created for the initial iPhone versions.

You cannot apply it to the latest versions. Instead, check some of nowadays reputable jailbreak sources, such as blog.iphone-dev.org.
