Apple recently rolled out its first iOS 4 firmware update (iOS 4.0.1) for iPhone 3G, 3GS and iPhone 4 users. iPhone 3GS and iPhone 4 users are requested to wait until iPhone Dev Team releases a jailbreak tool which can jailbreak iOS 4.0.1 on the said devices. However iPhone 3G users can easily jailbreak iOS 4.0.1 by using the latest version of Redsn0w (v0.9.5b5-5).
How to Jailbreak iOS 4.0.1 on iPhone 3G with Redsn0w 0.9.5b5-5
*Find download links at the end of post
- *Download iTunes 9.2.
- *Download Redsn0w 0.9.5b5-5
- *Download both iOS 4.0 and iOS 4.0.1.
- Restore iOS 4.0.1 IPSW using iTunes 9.2 to your iPhone 3G. Don't worry, it wont upgrade your baseband from 05.13.04. You will still be able to unlock it using Ultrasn0w.
- Once iOS 4.0.1 is successfully restored on your iPhone 3G, run Redsn0w and click on the "Browse" button. Select iOS 4.0 (NOT iOS 4.0.1) file you downloaded in step 3.
- Check "Cydia" and click on the next button.
- Check Enable Multitasking and Wallpaper. Please note that this step is optional, if you don't want to use these options, simply uncheck them.
- Turn off and unplug iPhone 3G from your computer.
- Connect your iPhone in recovery mode. For that you will need to quickly hold "Power" button , after holding the "Power" button for 3 seconds, you will now have to hold "Home" button for 10 seconds. After that release "Power" button but keep holding "Home" until the installation automatically begins.
- Now leave the rest for Redsn0w, your device will reboot automatically once the process is completed. You should have a fully jailbreaked iPhone on firmware 4.0.1
