Here are some important points to note before you proceed.
- This guide is meant for iPhone 4 and iPhone 3GS users. iPod touch users can checkout the iPod untethered jailbreak and iPad users can checkout iPad untethered jailbreak
- Important note to iPhone unlockers: Please don’t use this guide if you want to preserve your iPhone’s baseband. We will publish a guide for it shortly.
- Redsn0w 0.9.10b1 does not support iPhone 4S currently, but pod2G is working hard on it. We’ll keep you posted.
- Please note that jailbreaking your iPhone may void your warranty and hence proceed with caution and at your own risk.
- Please do not forget to backup your iPhone before you proceed. You can refer to this post for instructions on how to backup your iPhone.
- If you’ve jailbroken your iPhone then you can use jailbreak apps such as AptBackup, PkgBackup or xBackup from Cydia to take a backup of all the jailbreak apps and tweaks so you can reinstall them easily after successfully jailbreaking your iPhone rather then installing them individually. However, if you’re moving from iOS 4.x to iOS 5, it may be a good idea to reinstall the jailbreak apps to avoid compatibility issues.
- After the jailbreaking process is complete, do not forget to checkout our article on tips to keep your iPhone secure.
- Please ensure you are running latest version of iTunes i.e. iTunes 10.5 or later.
You can follow these step-by-step instructions to jailbreak your iPhone 4 and iPhone 3GS with the assumption that you’ve already updated your iPhone to iOS 5.0.1 (please note Settings –> General –> About –> Version should be 5.0.1):
Step 1: Download Redsn0w 0.9.10b1 for Windows from https://sites.google.com/a/iphone-dev.com/files/home/redsn0w_win_0.9.10b1.zip?attredirects=0&d=1 and Redsn0w 0.9.10b1 for Mac from https://sites.google.com/a/iphone-dev.com/files/home/redsn0w_mac_0.9.10b1.zip?attredirects=0&d=1 and save the application in a folder named “Redsn0w” on your desktop.
Step 2: Double click the Redsn0w zip file and extract the application to the Redsn0w folder. Navigate back to the Redsn0w folder and launch the Redsn0w application.
Step 3: After launching Redsn0w, click on the Jailbreak button.
Windows 7 users should run the exe in Windows XP compatibility mode (right-click on the Redsn0w exe and select Properties, then select the Compatibility tab and select Run this program in compatibility mode for Windows XP). Windows XP and Windows 7 users should run Redsn0w as ‘Administrator’ (right-click on the Redsn0w exe and select ‘Run as an Administrator’).

Step 5: You will now need to put your iPhone into the DFU mode. Redsn0w will take you through the necessary steps:
(a) Hold the Power button on iPhone down for 3 seconds:
(b) Now simultaneously hold the Home button and keep the two buttons pressed for 10 seconds:
(c) Now release the Power button while keeping the Home button pressed until Redsn0w detects the device:
Step 6: Your iPhone should reboot now. Please remember to release the Home button.
Step 7: Redsn0w will now start preparing the jailbreak data.
Step 8: You will now be prompted to select the jailbreak options you would like. Make sure Cydia is selected and select ‘Next‘ to continue.
Step 9: You iPhone will be rebooted again and Redsn0w will now begin uploading the new RAM disk and kernel.
Step 10: You will now be notified once the jailbreaking process is complete. Click on the ‘Finish‘ button to exit the application.
Step 11: Your iPhone will reboot once again (which could take approximately 5 minutes). After it has rebooted, your iPhone should be successfully jailbroken. You should find Cydia jailbreak app on your iPhone’s home screen.
