This is just a documentation, an idiot-friendly guide and collection of all necessary information needed to Unlock/Jailbreak. As an iPhone user, I would just like to repost the best solutions, share the knowledge and answers to our questions I found on the Internet in Unlocking/Jailbreaking iPhone 2G (First Generation).

What is Jailbreak?

Jailbreaking is a process that allows iPhone and iPod Touch users to run unofficial code on their devices bypassing Apple’s official distribution mechanism, the App Store. Once jailbroken, iPhone users are able to download many applications previously unavailable through the App Store via unofficial installers such as Cydia and Icy.

Note:

• This jailbreak guide is designed for Windows user.
• You can use this guide to jailbreak & unlock only iPhone 2G (the 1st generation iPhone)
• If you’re using lower version of firmware (e.g. 1.1, 2.0, 2.1 or 2.2), you can also follow the jailbreak procedures to upgrade the firmware to 3.0. But please note that you’ll have to re-install all the Cydia applications after upgrade. And, at the time I write this post, not all Cydia applications (e.g. Backgrounder, iRealSMS, MySMS, BossTool, Quickgold) are compatible with iPhone 3.0. So, if you have any cydia applications that you rely on, please ensure its compatibility before upgrading.

Now, let’s get started.

1. First, make sure you have upgraded to latest iTunes version and backup your iPhone data by synchronizing it with iTunes.

If you’re upgrading the iPhone from older version of firmware, make sure you sync the iPhone with iTunes. This ensures all your SMS, contacts and applications can be restored after the firmware upgrade.

2. Download Redsn0w 0.8, Bootloader 3.9 & 4.6 and iPhone firmware 3.0. Save them all in the same folder. And unzip redsn0w-win_0.8.zip. So make sure you have all the files in place before proceeding to next step.



Install iPhone software 3.0 via iTunes

3. Next, connect your iPhone to your computer via USB cable and launch iTunes. Select your iPhone in iTunes.



4. Now, hold the SHIFT key and click the “Restore” button. iTunes will launch a file dialog for you to select the firmware file. Locate the “iPhone1,1_3.0_7A341_Restore.ipsw” for iPhone 2G and click “Open”.



5. iTunes will then restore your iPhone with firmware 3.0 (or what so called iPhone 3.0 OS). Keep your iPhone connected, don’t touch it and wait until the process completes.



Jailbreaking with Redsnow

6. Now, your iPhone should be completely restored to firmware 3.0. But it’s not activated right now as you can see from iTunes.


So, what you’re going to do next is to use Redsn0w to activate and jailbreak it. But before proceeding to next step, please power off your iPhone (but keep it connected with USB cable).



7. Next, launch Redsn0w to start jailbreak & unlock.



8. Once launched, click the “Browse” button and select the firmware file that you have downloaded. For iPhone 2G, please locate the “iPhone1,1_3.0_7A341_Restore.ipsw”.



Redsn0w will then verify the firmware file. If it’s correct, redsn0w will show the message “IPSW successfully identified”. Then click “Next” button to continue.

9. Next, you’ll need to select the jailbreak option. For iPhone 2G, please select both “Install Cydia” and “Unlock” option.



10. Please select the bootloader files that you have downloaded in step 2.



Put in DFU Mode

11. Next, redsn0w will instruct you to put your iPhone into DFU mode. Ensure your iPhone is connected (via USB) and it’s turned OFF. If you’re ready, click “Next” to continue.



12. Follow the instructions to put your iPhone into DFU mode.

Tip:You may not be able to put the iPhone into DFU mode for the first trial. Don’t worry. Simply click the “Back” button to go back and try to follow the instructions again. Redsn0w will start the jailbreak process only if it detects your iPhone is properly put into DFU mode.






13. If you have successfully put the iPhone into DFU mode, redsn0w will automatically start the jailbreak process.





14. While jailbreaking, your iPhone will show downloading jailbreak data, flashing NOR, etc. And, just don’t touch your iPhone and keep waiting.



15. Once completed, redsn0w will let you know the jailbreak process is successful. Your iPhone will be restarted and automatically launch BootNeuter to perform unlock. This process will take 3-5 minutes to complete. Be patient. When complete, your iPhone will be rebooted.



16. Congratulation, you’ve completed the jailbreak process for iPhone 3.0 OS. As you can see from the home screen, you now get the new Voice memo application, which is introduced in iPhone 3.0.



17. Lastly, sync back your backup data with iTunes and restore all your contacts & SMS.

Enjoy :)
