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

** If you would like to jailbreak on the 3.0.1 firmware you can follow these exact instructions; however, in Step Two use 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 RedSn0wfrom 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 (3GS): iPhone2,1_3.0_7A341_Restore.ipsw

Extract the RedSn0w executable from the 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
RedSn0w will now instruct you on how to put your iPhone into recovery mode. Disconnect you iPhone 3GS from the computer then power it off. Then hold down the Home button while reconnecting the device to the computer. Don't let go of the button until RedSn0w detects the iPhone and begins installation.

Step Nine
Your iPhone will now reboot

Step Ten
RedSn0w will then begin uploading the new RAM Disk and kernel.

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

I am not a Macintosh/Apple fan, I use Windows/Linux/Android. However, I bought an iPhone 3G 16GB for $50 from a friend. I've Jailbroken it but now I face two problems. Cydia tells me that there are some Essential Updates to download and install but when I confirm the installation none of the files download successfully. I get an error for each one then I'm taken back to the Cydia main page. Secondly, now that I'm Jailbroken, when I plug in my iPhone and open iTunes it asks me to Setup as New iPhone or Restore from Previous Backup, until I choose one of these options I can't sync my iPhone to my PC and/or copy music over etc. Why? How can I get by this? After these problems are resolved I need to unlock the iPhone but I can't move forward until the Cydia issues are fixed... Help!!! PAinguIN

I bought a 3gs and I recieved it for 5 days ago, is it blocked against jailbreaking or what? I tried to jailbreak it but it wouldn't work, why is that?

Anton - December 19, 2009 at 3:12pm

Does this jailbreak method require a AT&T SIM card inserted in the phone? I'm getting a locked iphone 3gs and need to unlock it. Thanks.

mud_apple - October 11, 2010 at 2:11am

same thing happen with mine, plz help ....

disappointed - November 9, 2009 at 10:15pm

Nothing - December 18, 2009 at 1:42am

MINE TOO! nothing happened after i jailbroken it..so freakin pissed

Brad - December 19, 2009 at 3:17pm

If you have gotten a 3gs within the past 3 months there is a new block and they cannot be unlocked. Not sure if this is your problem but figured I'd let you know.

amanda - December 20, 2009 at 8:13am

Someone told me the new iphone3gs can't be jailbroken yet cause it will keep getting locked and that have to waiting for new programs? then how am i suppose to download bosspref to off EDGE? SOS

hey i just used redsn0w to jb but when i browse for iPhone2_1_3.0.1_7A400_Restore.ipsw it says unable to recognize specified IPSW what is the solution??? i have a 3GS iphone with 3.0.1 frimware baseband 4.26.08 and i have never JB or unlcoked

Jeff - October 22, 2009 at 11:31am

Ok with the newest pwnage tool out it is now possible to jailbreak a 3GS with 3.1 FW installed? All I need now is a mac right?

Mike - October 21, 2009 at 11:30am

Everyone who is having problems with downloading the IPSW files.... Download FireFox web browser and use it instead of Internet Explorer. Makes all the difference in the world. Works great every time. No problems.

Brad - May 27, 2010 at 5:49pm

Okay I followed all the instructions to a tee and I have a 3GS with firmware 3.0.1 and when I tried to load the new iPhone2,1_3.1.2_7D11_Restore.ipsw as it's extracting into my iPhone iTunes give me an error that reads 'The iPhone could not be restored. This device isn't eligible for the requested build. Any suggestions???

Ter11 - October 21, 2009 at 6:29am

Hi all can please someone confirm that it is safe to use this tutorial now that apple blocked restoring of old FW 3.0.x? So I just follow this tutorial WITHOUT first restoring to 3.0.1: I directly start with the jailbreaking-thing using redsn0w with FW 3.0.1 I installed on my so far non-jailbroken 3gs for weeks, ok? Thanks! Ter11

dan - October 19, 2009 at 10:19am

Hi, I have an iphone 3gs and was JB before but when the itunes 9 came it accedently upgraded to 3.1.2Fm and now I just cant unlock it, I did all I mean Blackra1n and then Cydia, and all goes ok, but then when I put my sim it says " searching" and then no network, so guys I really need help, what to do, am on windows vista, plzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz thanks

Mike - October 21, 2009 at 11:05am

You will need to restore your iPhone to an earlier backup file. IE: Pre 3.1.2 then be sure to download the proper ISPW file according to your iPhone. https://www.iclarified.com/entry/index.php?enid=750 Watch the video and follow the steps accordingly. FYI I have done several iPhones since the 3.1.2 update without any problems. I use the RedSnow software, it is the only one that I have found to be reliable. The others all have a problem. Such as your very problem. Torrent Client and Torrent Files that some use are not very stable. Try RedSnow and you should be ok.

Daniel - October 18, 2009 at 6:02pm

I understand that the restore option will erase everything on my iphone, and then I'll have to reinstall all apps and re-define all my email accounts etc? Thank you.

Tom - October 8, 2009 at 2:27am

I tried to jailbreak my iPhone 3GS with OS 3.0.1 and when restoring (using either the xxxA400_Restore.ipsw or xxxA341_Restore.ipsw file with Shift+Restore) I received the error message that "The iPhone could not be restored. This device isn't eligible for the requested build.". If I understand the support at the Apple website correctly this is due to the fact that Apple doesn't allow a restore of an older OS version and OS 3.1 is out already. Unfortunately the iPhone is already in recovery mode since my office computer didn't allow the access of the Apple server(s). If I use the Restore thze iPhone will be updated to OS 3.1 which as of now can't be jailbreaked with a Windows machine. Does anybody have an idea how to proceed since I cannot use the phone at all at the moment?

chris - October 8, 2009 at 2:02pm

im having the same problem 3gs 3.0.1 try to restore and same message.using latels itunes. any news on this?

Brad - October 20, 2009 at 7:02pm

i'm getting the same message! did anyone find anything out? thanks. bradgoldfinger@gmail.com

Mike - October 21, 2009 at 11:07am

Brad - October 21, 2009 at 11:20am

I've tried RedSnow and I've tried to restore to 3.0. When I try to restore to 3.0 it comes up with the error "device isn't eligible for requested build". Used Saudik's rerouting to try and trick itunes by changing the IP in the "hosts" file, but no luck. Can't seem to get around the restore. I just got the 3gs yesterday, so I'm not sure if there has been a more advanced block by Apple.

Kevin - September 30, 2009 at 8:22pm

I download the FM but when i go open it with my Iphone restore its not in the folder. I have re-downloaded it 3 times. In the tutorial it shows its just one ispw file but when i download it its a zip file and no ispw inside of it. What is wrong?

Jeff - September 30, 2009 at 10:17pm

There is something wrong with your download. Make sure you are extracting the file. If all else fails try using a different browser (i.e. Firefox).

Alex - October 1, 2009 at 10:50am

Same here it is a zip file not a ispw file. What should I do to this file to make it to an ispw so i can do the Jailbreak?

marcelo - October 19, 2009 at 10:23pm

anyone can help us? i have the same problem

simplicity168 - November 20, 2009 at 10:35pm

Change the extension from .zip to .ipsw I presume U were using a DownloadManager.. GoodLuck.. :)

Jeff - September 29, 2009 at 4:07pm

Alright, newbie here! Bought my iPhone today with version 3.1 preinstalled. I've downloaded the 3.0 FW, attempted the restore and it gave me the sane error others have said below. Knowing this, I skipped step 1 and 2 and ran redsn0w. Everything checked out, disconnected the USB and restarted while holding the Home key and reconnected the USB once the iTunes and USB cable showed up on the screen. redsn0w auto detected this and continued. It finished and "Done!" appeared so I clicked Finish. Heres the thing, the iPhone didn't reboot so I manually rebooted. Once it came back up no Cydia. I even tried restoring to Apple's 3.1 and starting over fearing that my initial sync may have caused some issues. After restoring I tried it again and still nothing. Please help!

Mike - October 1, 2009 at 10:33am

You can't jailbreak an iphone 3Gs that has 3.1 firmware yet just 3G and 2G. The firmware restore doesn't work the way you think it does.

Jeff - October 1, 2009 at 5:16pm

So I'm screwed until the newest pwnage tool is made and released.....

maks - September 26, 2009 at 7:32am

hi! when the jb is finished, can I unplug the iphone directly and reboot it manually? or does it reboot automatically?

Mario - September 25, 2009 at 12:43pm

CAN i APPLY a jailbrake after my iphone is already Jailbraked ? (iphone 3Gs FW 3.0.1) When jailbraking will my iphone data be deleted ? Since itunes dont permit to restore FW lower then 3.1

Mario - September 24, 2009 at 7:01pm

Hello PPL! Question 1 Since apple blocked installing FW previous than 3.1 can i still restore with a 3.0.1 version? Question 2 Why cant we just run redsnow to jailbrake ? Why do we have to run itunes and make a restore? Imagine i have my iphone already with FW 3.0.1..wouldnt be enought to just run redsnow?

Mario - September 24, 2009 at 7:13pm

Ok.. just saw ahead the solution.. start jailbraking using only redsnow and skip itunes restore step! BUT now the MILLION DOLLAR QUESTION IS: If i install apps...etc.etc... and in future my phone gets hang ups or not working well, will i be able to "RE-JAILBRAKE-IT" over the jailbraked already ? What i mean is: can i apply again redsnow and the iphone goes back to its original point (with no apps etc) and jailbraked ?

Bonbon - September 25, 2009 at 3:01am

OK. THis is what I did to jailbreak my new 3Gs. I just bought it today with the FW 3.0.1. I followed the tutorial and got the message saying "device isn' t eligible for the requested build". So I skipped the Shift and Restore part. I went straight to step 3 and use the restore 3.0 instead of the 3.0.1 because Redsn0w does not recognized 3.0.1. And then follow the rest of the steps and BAM, jailbroken! So far my phone is working.

maks - September 27, 2009 at 5:21pm

i did exactly the same but mine doesn't work anyway :/

nick - September 28, 2009 at 10:57am

i did the exact same thing as well and it shows no sign of cyndia or of any sign of change at all .. help ? :(

Ces - September 23, 2009 at 2:59pm

I dont get it .... I did this jailbrake for 2 people 3 weeks ago and it worked fine.... Now I'm doing it for me since my old 3gs was thrown in a pool and now i have another one..... In itunes I hold down shift then restore ...select the firmware .... then it says my iphone isn't eliable for the requested build.... can someone help

bilutza - September 24, 2009 at 11:36am

To do a restore the fw must be signed by Apple and now Apple signs only 3.1. You may try to jailbreak without restoring, I don't know if it works, maybe somebody tried already... Otherwise you'll have to wait for a 3.1 jb and then restore/jb to 3.1

maks - September 25, 2009 at 5:35pm

i think you should skip step 1 and 2.is that right? anyone who knows?

dkcirtap - September 23, 2009 at 4:12am

Excellent posting worked first time on a Iphone 3GS 3.0.1 thank you very much

Meis - September 21, 2009 at 3:30am

OS 3.1 has been released. This means that when I try to restore my iPhone 3GS 3.0.1 to OS 3.0 or 3.0.1 I can't - the only option is to restore AND update to 3.1 which I do NOT want to do. Is there a safe way of jailbreaking my iPhone that does not involve putting it into recovery mode and at risk of updating to OS 3.1 I have not been able to grab my IBSS or IBEC due to the 3.1 issue. Am I stuck?

Petr - September 22, 2009 at 10:54pm

switch your iphone off then switch on and keep menu button pressed while connecting iphone to PC keep untill itunes appeares then realase menu button keeping shift pressed , press restore.... you will be offered to restore from a hard drive

Meis - September 23, 2009 at 12:42am

That doesn't work anymore, it did maybe a month ago, but now when you select from a hard drive it will start restoring to a previous OS but will then come up with an error message... hence my issue. Thanks though.
