Guide: Jailbreak/Unlock iPhone 3.0 using Redsn0w for iPhone 2G
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.
- First, make sure you have upgraded to latest iTunes version and backup your iPhone data by synchronizing it with iTunes.
- 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.
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.
