These are instructions on how to jailbreak your iPhone 3G on the 4.0 or 4.0.1 firmware using RedSn0w for Mac and iTunes 9.2. The Windows 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. It will also hacktivate your device for those not with an official carrier.

Step One
Create a folder on your desktop called Pwnage

Download RedSn0w from here or here and place it in the Pwnage folder. Likewise, download the latest 4.0 firmware from below and place it in the same folder. If you wish to update to 4.0.1 you will need to download this firmware as well.

4.0.0 (3G): iPhone1,2_4.0_8A293_Restore.ipsw
4.0.1 (3G): iPhone1,2_4.0.1_8A306_Restore.ipsw

Extract the redsn0w app from the RedSn0w zip file by double clicking it.

Important: If you wish to remain at 4.0 then skip Step Two.

Step Two
Connect your iPhone to the computer and launch iTunes.
How to Jailbreak Your iPhone 3G Using RedSn0w (Mac) [4.0, 4.0.1]

Verbose boot displays detailed information on boot of your device and is generally only needed by developers and advanced users.

Make sure Cydia is selected. For this tutorial we will also select Custom boot logo and Custom recovery logo.

When you click to select each custom logo option a dialog window will appear asking you to select the image. Locate the image you would like to use then press the Open button.

*Remember the rules for boot logos are: RGB or Grayscale format with Alpha channel and dimension below 320x480. If you would like to use the iClarified ones they can be found here: Boot Logo, Recovery Logo

Notice that RedSn0w has already selected to Enable multitasking, Enable homescreen wallpaper, and Enable battery percentage. If you do not need multitasking we would recommend deselecting it as it makes your iPhone 3G run very slow.

Click the Next button to continue

hello folks, made sure to read thru all the threads before posting...i have an unpwned iphone 3g running 3.1.3 and trying to jB (then uL). 1. when i try to update as in step #2, i get the error "iPhone could not be restored because the firmware file is not compatible" -- do i need to update to iOS 4 via iTunes *first* and then begin this process? my understanding is that i would upgrade after going thru these steps. 2. after antennagate, itunes is now updating to iOS 4.0.1 -- will this update work or should i wait for an update from idev team (who i need to thank!)? thanks, in advance, for the help.
aelly - October 6, 2010 at 10:57pm

Be advised that redsn0w 0.9.5 Beta is out. It worked well when I JB my 3G. The previous vers. had some issues with 4.0 OS. Seems to have been fixed. Also, I just noticed the tutorial link to redsn0w is down. iC may be updating the link. Cheers!

New Download link please!!!!

Maybe a strange question: do I need to update to iOS 4.0 via iTunes 9.2 first before jailbreaking with RedSnow and then unlocking, or can I run RedSnow with the new IOS 4.0 while my iPhone 3G is still on iOS 3.1.2 with Baseband 4.26.08?
Justin - July 6, 2010 at 4:50pm
You update via itunes to 4.0 using the method in the tutorial ("Hold down Option and click the Restore button"). I followed this tutorial step by step and it worked fine. Once finished I checked my version and baseband and all was updated to the latest (i.e 4.0 w/ BB 5.13...). I was on 4.26 and firmware 3.0 to start. I'm assuming there is no way to upgrade to 4.0 w/out upgrading the baseband along with it (if there is, this tutorial doesn't cover it). However I jailbroke just fine and then installed Ultrasn0w w/out issue.

After Jailbreaking & unlocking, is there a way to go back to the original locked 4.0 firmware that I'm currently running. I just need to go out of country for 3 weeks, and I need to use another sim on the phone; and when I come back, I want to be able to use my phone the way it is before unlock&jailbreak (feel more comfortable) If the answer is yes, then how do i do this? Restoring in DFU or Recovery? -By doing so, do I lose any data (such as txt, contacts, applications etc) between the time of jailbreaking and restoring to locked firmware (since i have a backup prior to jailbreak) -Can I continue to backup/sync my device the usual way after I jailbreak it? -When I restore the device to the locked firmware, should i use my backup taken prior to jailbreak, or can i just use the one i have while it was jailbroken?

Hey guys. Has anyone had troubles downloading ibooks and making it works? I have an iphone 3G on 4.0 version, but it never downloads any ibook and it just crash, it syncs with my Mac but with I try to open it from the iphone, it doesn't work. Do you have any ideas? Thanks for your help.
billybnyc - June 28, 2010 at 5:08pm
I can't seem to get pass the second "Waiting for reboot". Anyone have any ideas?

3G on 3.0 jailbroken/unlocked (BB 4.26) iTunes 9.2 on MAC - Great tutorial first off. However before I attempted the upgrade to 4.0 I disconnected my internet connection in fear that it may reach out to Apple servers and lock me down...sure enough, during step 2, after manually selecting the IPSW to restore from I got the error message: "The iPhone cannot be restored at this moment because the iPhone software update server could not be contacted or is temporarily .." Am I ok to reconnect and continue? What's it need the Apple servers for if I'm restoring from the file? Any insight is appreciated. Thx
Justin - June 28, 2010 at 8:49pm
In case anyone was wondering: I ended up connecting back to the net and going through with it all. Everything works perfectly fine, followed the tut step for step and everything went just fine. It did upgrade my baseband to 5.13 but I guess that is normal if I'm upgrading the OS to the newest version...? Ultrasn0w currently unlocks the 5.13 baseband so it doesn't matter anyway. Works great (didn't do enable the multitasking though). Now my 3G is updated/jailbroken/unlocked and ready to sell! (Proud owner of the iPhone 4) TUT was great, thanks again.

Does anyone else have an issue with tethering after jailbreaking with RedSn0w. I've tried it twice already. First, after the restore of new iOS4, I tried tethering and it seems to work. After jailbreaking, the option exists for the first time, but once I enable the tethering, the option disappears. And even though Itunes asks to update the carrier information, it still doesn't give me the option to tether.

Visual Voicemail not working after Jailbreak. Running iOS4 on iPhone 3G 16GB Black. iTunes 9.2 and OSX 10.6.4
Mynameismud - June 24, 2010 at 12:58pm
Thank you! This tutorial worked GREAT! Thanks so much for this, it made my JB experience pleasurable. Too bad it took me 2 days of banging my head against forums before I found it. It made me more confident in jailbraking. Everything went smoothly and exactly as the tutorial showed. Thanks again. Hooray multitasking!

HELP HELP PLEASE HELP!!! I have an IPhone 3G and it was on OS 3.1 Jailbroken. I am trying to resotre it to IOS 4.0 using the above IPSW and the phone starts restoring and in Itunes the restore does not complete. The status bar is 99 % complete but it does not finish. I have left it running over night to no success. Am I missing something here? Anybody else have similar issues? I am on BaseBand 4.26.08 do you think if I update directly through itunes to 4.0 I will loose the baseband? Any help will be appreciated.

Yes put iPhone in recovery mode and restore it in iTunes
Mauricio - June 23, 2010 at 7:27pm
Hi, just did the restore on the iPhone, but the home button and the power button doesn't seem to be working at all... sometimes I can turn it off, some times not, if I enter an app I can't get back to the home screen... I was not able to put it into DFU mode yet due to this... anyone has any idea?
Ciprian - June 23, 2010 at 3:28pm
It was because of Winterboard So ... till an update for WB ... I guess is some conflicts between WB and iOs 4
CAPS - June 23, 2010 at 10:53am
Hey guys, one big big and I guess stupid question. I have a jb iPhone on 3.0 firmware and 4.26 baseband. Does this tutorial apply or I do need to upgrade to 3.1.2 or 3.1.3 first. Thanks a lot
Mo - June 23, 2010 at 12:54pm
Nope, you can go ahead and do it directly.
