These are instructions on how to jailbreak your iPhone 3G on the 3.0.x iPhone firmware using RedSn0w for Windows. The Mac version of this tutorial is here. The 2G version of this tutorial is here

This tutorial can be used to jailbreak before applying the UltraSn0w unlock.

** If you would like to jailbreak on the 3.0.1 firmware you can follow these exact instructions; however, in Step Two restore using this 3.0.1 iPhone firmware file instead of the 3.0 one. Continue with the instructions as indicated.**

Step One
Create a folder on your desktop called Pwnage

Download RedSn0w from here and place it in the Pwnage folder. Likewise, download the latest 3.0 firmware from below and place it in the same folder.

3.0.0 (3G): iPhone1,2_3.0_7A341_Restore.ipsw

Extract the RedSn0w zip file to the Pwnage folder.

Step Two
Connect your iPhone to the computer and launch iTunes.

Select your iPhone from the list of devices on the left. Now hold down shift and click the Restore button. Restore is preferred as it won't create any wasted space on your iPhone.

Navigate to the Pwnage folder on your desktop and select the firmware ipsw. Click the Open button to continue.

Step Three
Once iTunes has finished updating your iPhone to the desired firmware you may launch redsnw0w.exe from the Pwnage folder on your desktop.

Step Four
Once RedSn0w opens click the Browse button

Step Five
Select the firmware ipsw we placed in the Pwnage folder on our desktop then click Open

Step Six
Once the firmware has been verified click the Next button to continue.

Step Seven
Make sure Cydia is selected and click the Next button.

Step Eight
Please plug your iPhone into the computer and make sure its OFF then click the Next button

Step Nine
RedSn0w will now guide you through the steps to get into DFU mode.

Hold down both the Home button and the Power button for 10 seconds.

Release the Power button and continue holding the Home button until RedSn0w detects the device.

Step Ten
Your iPhone will now reboot

Step Eleven
RedSn0w will then begin uploading the new RAM Disk.

Step Twelve
Once this is complete you will be notified that RedSn0w is done. Click the Finish button.
When your iPhone finishes reboot (5 minutes or so). It will be jailbroken with Cydia on the SpringBoard.

After pressing save as, Change the file type (lowest box in window) to all files from.zip. It will then save as you need it. N.B. Ensure the file name ends .ipsw If not manually type it in before saving.

OMG! I finally got to see the video. It kewrod perfectly on my home computer. I LOVED IT!!!!!!!! And the music was SO PERFECT only you could make me happy, only you could make me smile. I was so sad when I lost Dillon, then Phillip's face entered my life and I smiled when I saw it. And when I got him from Dobie Rescue I could once again be happy. That is an amazing video, an amazing portrait, a perfect song to celebrate it all. YOU are an AMAZING artist/person. I am so blessed to have met you and have you in my life!

If my phone is already 3.0 frimware do i still need to use it ?

Torrentmastah - January 13, 2010 at 7:31am

Hi When you choose "iPhone1,2_3.0.1_7A400_Restore.ipsw" in redsn0w and you get the error message "Unable to recognize specified IPSW" choose "iPhone1,2_3.0_7A341_Restore.ipsw" instead and it should work. If redsn0w 0.8 crashes in Vista when you try to jailbreak then right click on redsnow 0.8.exe and go to properties and in there go to compatibility there set it to "windows xp service pack 2" and then go down and check the "run as administrator" Run the process again and it should work. It worked it for me Hope this to some help.

i suggest not updating the carrier settings after the jailbreak. I launched itunes and it prompted me to update the carrier settings i did it and I couldn't connect to the network overseas anymore so i have to restore the software with itunes and the backup which took another hour or more.

Jacob - January 2, 2010 at 2:36pm

Worked Great ! Thanks

Thank you very much for this very helpful thread, now my iphone 3g is updated to OS3.0, jailbroken and unlocked. Even the comments and reply to the comments were very useful. Thanx to iclarified and to all those who shared helpful insights in the comment section.

Hi Francis, you might need winzip or winrar to extract the folder.

Dhruva - November 27, 2009 at 2:08pm

Hi Yank, From what I understand, you need to unlock your phone. This tutorial is only to Jailbreak it, so now that you have done that well, find the tutorial that teaches you how to Unlock your iPhone 3G. That should solve you prob. Good luck!

yank - November 29, 2009 at 12:25pm

hi dhruva thanks a lot 4 replying man

matoh - January 23, 2010 at 3:20pm

hi i have the same problem. did u solve it plz? if so could u advice me how? THNX

Dhruva - November 9, 2009 at 1:38pm

I have a 3G j/b and unlocked iPhone (I j/b and unlocked it when it had 2.2 s/w and baseband was 2.28). After that, I tried re-jailbreaking it and unlocking it to the 3.1.2 with blackra1n. Nothing happened, literally nothing (I'm guessing since the baseband wasn't at 5.11). Then I read details on redsn0w using this tutorial (to j/b and unlock to 3.0.1). I tried that method, but accidentally (i KNOW! crazy huh!) updated the phone to 3.1.2 through iTunes (using a custom ipsw from iClarified though, pressing shift+restore). Now I can't get the phone to work. So both redsn0w and blackra1n didn't work for me because of the accidental update. Is it possible to fix it? Perhaps wait for the next release, or is it of no use? Any help would be REALLYY appreciated. please! Thank you.

Ricki - November 2, 2009 at 6:44am

Does this work on firmware 3.1.2?

Dhruva - November 9, 2009 at 1:41pm

Nope, only the 3.0.1 (or 3.0) for now. Try using blackra1n (there is a tutorial on it), but make sure you read it fully before trying it. or best to just use redsn0w and update to 3.0.1 (depending on ur iPhone's status right now). It is better to check if it matches your iPhone's specifications before using it. Hope this helps.

Jessica - October 6, 2009 at 5:01am

Need some HELP, Please....... I've the 3G 3.1 version now. The problem is, I can't restore the 3.0 version. So I skipped the first step, then I continue to the Step where I have to click on the Redsnow folder and browse the firmware. I finished all the step, but, by the time my Iphone restart, I still couldn't find the Cydia apps on my Iphone screen. and I lost all my applications. So, i re - jailbreak again, by re- doing the step 3 till finish. What i found in my Iphone screen when it's restarting is an image of a biten pineapple with the words, 'Installing Bundles' . What is that mean? So, what can I do to have the Cydia Apps ? Do i need to dl anything else after this steps ? Anyone can help me, pls... Thanks alot!!! ^^

keviej - October 29, 2009 at 11:55am

Where did you get the 3G 3.1 firmware from. I downloaded the firmware from the instruction but it isn't appearing when I try installing it.

IMatrix - October 5, 2009 at 10:06am

Hi guy, I'm from Argentina. I'm trying to jailbrake my new Iphone 3G but it seems imosible. Y have the last baseband (05.xx.xx) and Filware 3.1. I did all the steps in this tread but Itunes cant finish the restore, cause show me error 1015. I read that it's fine that error, is beacuase i'm trying to downgrade the phone. So I start the RedSn0w, do all the steps and look's like all will work. The problem is we the jailbrake finish the Iphone reboot and get stuck in recovery mode, so I cant use the phone. The only way to reuse the phone is using the recovery from itunes (witout using Shit+Filmware i download). Also try to restoring from itunes with DFO mode.... but show me the same error. Anyway I did all the steps and when the jailbrack was finished the iphone kept on recovery mode. I hope you can help me, I commend you for this page. Thax
