Jailbreak for 4.0 firmware

Jailbroken 4.0 page (Cydia+Files)

Description: 

This is a guide that works for the following: 

• iPhone 3G and iPod touch 2G only
• Mac OSX x86 and Windows
• the 4.0 official FW only
• Non-MC iPod Touch models (Settings=>General=>About screen=>Model)

Do not try this on any other iDevice, firmware or computer. This is a “Beta-version” that is why it works on specific devices; another guide will come out with new Jailbreaks. Ok so let’s get started!!! 

Steps: 

1)   Update your iTouch or iPhone regularly on iTunes (You may need to upgrade your iTunes to 9.2 beforehand) to 4.0 firmware (On your iDevice summary page). 

2)   Download redsn0w 0.9.5b5-2 for Windows or Mac. 

3)    Unzip the redsn0w file and open the redsn0w.exe file in the unzipped redsn0w. 

4)   After you opened your redsn0w press the “Browse” button and locate the 4.0 firmware you downloaded on iTunes (On windows: My Computer\Local Disc (c:) Documents and Settings\<Your User>\Application Data\Apple Computer\iTunes\iPhone Software Updates.                                                                      

On Mac: ~/Library/iTunes/iPhone Software Updates) And OPEN IT!!! 

5)   When it finishes recognizing the firmware it will ask you    if you have an iPod Touch 2G Mc-Model you obviously click no. 

6)   Next you click “Next” at the bottom and it will do some processes (“Preparing Jailbreak data”) and you’ll get a window with options of what you want the redsn0w to do to your iDevice. Check the first one (Cydia) and the rest choose what you want (I advise to check the bottom three). 

7)    Press “Next at the bottom and the program will ask you to make sure your iDevice is churned off and plugged in. 

8)   Then when you press next the program will show you how to get into DFU mode (10 seconds holding both home button and power button, and then 30 seconds holding only the home button). THIS may take a couple of tries but you’ll manage in the end. 

9)   From here till the part where you have Cydia the program will do it’s thing. FO NOT disconnect or touch your iDevice in this process! 

10) So after you saw the pineapple running on your iDevice and you saw the apple logo and everything’s finished, press the home button and open your jailbroken iDevice! 

11)  Cydia should be on your second page so open it. The first time you open it it’ll do some “Reorganizing” and may close, but when you open it the second time it’s the Cydia we all love!!! (To download Rock from Cydia see this article).
