This step by step guide will show you how to jailbreak your iPhone iOS 4.2.1 with RedSn0w. This tutorial was made using an iPhone 3GS but the steps are the same, no matter what device you are using…

 

Step 1: Make sure iTunes is updated to its latest version. Make sure your iPhone is on 4.2.1. If not, update it via iTunes.

 

Step 2: Download RedSn0w 0.9.6b4 and the firmware for your device (downloads at bottom)

 

Step 3: Launch RedSn0w and browse for the firmware you downloaded in step 2.

 

Step 4: Select to Install Cydia.

 

Step 5: Make sure your iPhone is turned off and plugged in your computer. If it’s not, plug it in, then turn it off. Click next, and be ready to get your iPhone in DFU mode.

 

Step 6: Hold the Home and Power button together for 10 seconds. Release the Power button while still holding the Home button for a few seconds.

 

Now if you have a newer device such as the iPhone 4, every time you reboot your iPhone, you will have to launch RedSn0w and choose the “Just boot tethered right now” option to boot your iPhone.

 

Step 7: Your iPhone will run lines of codes. When it’s done. Click Finish. You’re done!
