Update: For iPhone 1st generation / 2G running 3.1.2 go here.
Here are the steps to jailbreak and unlock iPhone 3G/3GS running on OS 3.1.2 modem firmware v 5.11.07 with blackra1n:
Before starting these steps, make sure you’ve updated to OS 3.1.2 from iTunes

- Now click on the Windows Logo, to download the Windows version.
- Save the blackra1n.exe and Plug your iPhone.

- Once it is saved, right click and select open, or you can also browse to the path where you saved it and open the exe.

- As soon as you launch the blackra1n.exe, you will see a big button with caption ‘make it ra1n‘, click on that button.


- Now your phone will be entered in a DFU mode and you will see Geohot’s photo on your iPhone screen and in the meantime you will also see iTunes saying to restore the phone: just ignore it.

- Let your iPhone reboot.
- Once it is rebooted, you will see blackra1n on your iPhone screen, open it.

- Now you will see 3 things: Cydia, Rock and sn0w.
- Tap on sn0w, but before doing that makesure you are connected to WIFI.
- It will install blacksn0w and will unlock the network.
- Similarly again launch blackra1n and install Cydia and if you want Rock select it.

- Thats it you are done, You will also see your Carrier name.
How long should it take for my phone to reboot? It’s been about 5 minutes now and the scare guy is till staring at me!

Hi I have got the new iPhone 3GS and have break as per the procedure u mentioned above. Everything seems to be working fine. Only problem I am facing is when I reboot the phone I have to run the blackra1n.exe on my system to get this started. Do you have any solution for this.
Hi I appreciate if someone can reply to below querry : (Hi I have got the new iPhone 3GS and have break as per the procedure u mentioned above. Everything seems to be working fine.

Satrian: this is an unusual issue ur facing, as I have iPhone 3GS I did follow the steps on this post and Jailbroke and unlocked my handset. Try the steps with screenshot at http://www.iclarified.com. I’m sure it will help u.
Satriani: once u logon to the site there is an option for Tutorials select that then select iPhone and then steps to jailbreak & unlock iPhone 3G/3GS Windows or MAC whichever OS ur using. Step by step with screenshot. I’m sure it will help u resolve the issue.
So, I’m getting blank screen whenever i try to use blackra1n…it says “done, wait for reboot” and then nothing happens (I’ve tried waiting over 10 minutes and doing it over and over again, but nothing seems to work)…please help!
@Andie I was facing the same issue when I was trying to Jailbreak a friends iPhone 3G. What I realized was that I was logged in secondary profile on Windows. I logged in to Administrator Profile on Windows and it worked fine. Make sure ur logged in to the Administrator profile. I cannot tell u it will work 100% but this is what had happened. Try it! Good luck buddy.. Happy Jailbreaking….!
Hey Ishfaq, thx for your help mate. I surfed the link http://www.iclarified.com and found a comment which says: “For those with the new iPod touch or a new iPhone 3GS, BlackRa1n only supports a tethered jailbreak. This means that once jailbroken you should not let your battery die. If it does die you will need to reconnect it to the computer and use BlackRa1n to boot it.” Can you suggest how could i overcome this problem??
@ Satrian_07 To make it unthetered jailbreak the iPhone twice repeatedily, I had read it some where I can’t remember it now. It shud definitely work. Follow jailbreak process twice back to back. Let me know if it works? I’m not 100% sure but I remember I did the same after reading it somewhere.
