These are instructions on how to jailbreak your iPhone 4 on the 5.1.1 firmware using RedSn0w for Mac.

This procedure will cause you to upgrade your baseband potentially ruining your chances for an unlock. Please follow this tutorial to update to iOS 5.1.1 using a custom ipsw if you need an unlock. It may be prudent to save your SHSH Blobs by following this tutorial before continuing.

If you want to jailbreak a lower firmware version you can find the appropriate tutorial here.


Step One
Create a folder on your desktop called Pwnage

Download the latest version of RedSn0w from here and place it in the Pwnage folder. Likewise, download the 5.1.1 firmware from here and place it in the Pwnage folder. (Note: you do not need to download the 5.1.1 firmware if you are already on iOS 5.1.1)

Extract the RedSn0w zip file by double clicking it.

Help with Iphone 3GS (bought in Denmark). I have an Iphone 3GS i got from a friend who updated and bricked a previously unlocked phone. It has baseband 06.15.00 and firmware 5.1.1. I jailbreaked using Redsn0w, installed Ultrasnow fixer and then ultrasnow 1.2.5. After that "no service" so I flashed ipad baseband using Redsn0w. After that a carrier (not mine) showed up for a few seconds but then again "no service". If i look in network selection 3 carriers pop up (not mine) and if I try to choose one it says "restrictet network". Ideas anyone ???

Since Apple is no longer signing iOS 5.0.1, Is it possible to upgrade iPhone 4 from iOS4.x to 5.0.1? Nir Hus MD., PhD.
