These are instructions on how to jailbreak your iPhone 3GS on the iOS 5.0 firmware using RedSn0w for Windows. The Mac tutorial is here.

This procedure will cause you to upgrade your baseband potentially ruining your chances for an unlock. Please wait until we have posted a tutorial on how to update to iOS 5 using a custom ipsw if you need an unlock. The jailbreak is also tethered for all devices except the old bootrom iPhone 3GS which means you will need to connect your device to the computer each time you reboot. Finally, it may be prudent to save your SHSH Blobs by following this tutorial before continuing.

If you want to jailbreak a lower firmware version you can find the appropriate tutorial here.

Step One
Create a folder on your desktop called Pwnage

Download RedSn0w 0.9.9b6 from here and place it in the Pwnage folder. Likewise, download the 5.0 firmware from here and place it in the Pwnage folder. (Note: you do not need to download the 5.0 firmware if you are already on iOS 5.0)

Extract the RedSn0w zip file by double clicking it.

Step Two: (Skip this step if you're on iOS 5 already)
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 5.0 firmware ipsw. Click the Choose button to continue.

iTunes will now update your iPhone to the new firmware.

Step Three
Launch the redsn0w application from the redsn0w folder we extracted earlier.

**Windows 7 users may want to try running the redsn0w executable mode as an administrator in Windows Vista compatibility. You can do this by right clicking the executable and selecting Properties from the contextual menu.

Step Four
Once RedSn0w opens click the Jailbreak button

Step Five
Plug your iPhone into the computer and make sure its OFF then click the Next button

Step Six
RedSn0w will now guide you through the steps to get into DFU mode. You can find more help with DFU mode here

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 Seven
Your iPhone will now reboot

Step Eight
RedSn0w will prepare the jailbreak data.

Step Nine
Select Cydia from the list of options and click Next.

Step Ten
Your iPhone will now be rebooted again and RedSn0w will begin uploading the new RAM Disk and Kernel.

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

BOOT TETHERED
Once you have jailbroken you will need to rerun redsn0w to boot tethered.

Step One
From the main RedSn0w menu click the Extras button.

Step Two
Select Just boot from the Extras menu to just boot tethered.

*As usual a big thanks to the iPhone Dev-Team and Geohot for their hard work and contribution to the iPhone community.

dear all, I've just successfully updated my iphone 3gs to ios 5, but the issue is that " after installed ultrasnow, the sim still could not recognize". Has anyone ever faced up with this problem? please share me your experience. Thank in advance.

Will redsn0w autodetect my bootrom version?

Josh - October 27, 2011 at 2:43pm

Can anyone comment on the Battery Life and performance on a Old Bootrom 3GS? Thanks

hey guys i got a problem , i have 3gs with old bootrom, i used the custom firmware made by (sn0wbreeze-v2.8b8), using windows 7, then i used that custom firmware to shift restore using itunes. Then everything went well. Then device started i was using t-mobile, which it cannot activate then i used (redsn0w_win_0.9.9b6). but when i select the custom firmware made by snowbreeze it says, firmware not recognised. Then i used STOCK firmware and which was identified, and proceed the jailbreak with that. along with jailbreak i selected install ipad baseband and hactivate. But when the process finished. i still have to go through the activation process using authorised sim. Also i tried the methods to buypass the activation by dailing 112 in emergency call. if worked couple of times. then screen would go black and again i was out of phone. I also tried using three fingers to swipe in the emergency call windows while voice over is active. but the notification bar did not appear. The bottomline is i cannot get into my phone using t-mobile simcard. Any help is appreciated?

I had a perfectly working unlocked and jailbroken iPhone 3GS, but of course I had to go ahead and try to get iOS5 on it. I didn't know I need to preserve my baseband while updating it, so now ultrasn0w will not unlock it for me and I'm left without a phone line. Is there any way to unlock an iPhone 3GS with 05.16.05 baseband? If not, is there any expected change that will allow me to do so?

Kev - October 18, 2011 at 9:16pm

The supported basebands for the iPhone 3G and 3GS are 04.26.08, 05.11.07, 05.12.01, 05.13.04, and 06.15.00. The baseband supported for the iPhone4 is 01.59.00. (from the Dev teams website, I dont think that there will be support for any other basebands just yet, especially not for the 3Gs, as we have been waiting for that for over a year. I just upgraded, jailbroke and unlocked my 3Gs and had to put in the ipad baseband, I just this minute did it, all seems to be working ok, but I cant vouch for the GPS at the moment until I try it tomorrow .. there have been reports that the ipad baseband messes up the gps

Kev - October 18, 2011 at 9:18pm

But an iPhone without GPS is better than an iPhone that doesnt make calls ...

Kev - October 18, 2011 at 9:20pm

Just checked GPS on maps and it pinpointed me exactly, so i will take that as GPS working for me.

Kev - October 18, 2011 at 6:50pm

Quick question 3Gs on 06.15.00 baseband, I already upgraded to iOS5 with sn0wbreeze and unlocked with ultrasnow, and although the phone is working fine, everynow and then the signal drops, and I loose wifi, then a few seconds later it comes back My question, if I jailbreak again with redsn0w, as I am on 06.15.00, will I still be able to unlock with Ultrasn0w Thanks in advance for your help Billy

Kev - October 18, 2011 at 9:22pm

Update. Just updates to iOS5 following the tutorial here, ipad baseband, all working fine, no calls dropping, and GPS seems to be working now.

planka - October 18, 2011 at 6:11pm

Could anyone please feedback on this is working or not? "The jailbreak is also tethered for all devices except the old bootrom iPhone 3GS.... " Does it get untethered? Any other problems? Is it slow on a 3gs?

long - October 18, 2011 at 3:42pm

Dear jailbreaker!! my phone is Iphone 3gs, and it is on the old bootrom. The question is that Can I still update my phone to ISO 5? and another problem is that I always encounter with error 3194 while I'm trying to restore 4.3.3 as well as 4.3.5. Can u solve this problem for me? In fact, I am very appreciate with Iphone dev-team that always provide the features for all iphone user! Hopefully, You'll solve and reply me asap. Thank in advance!!!

1. Add the following entries into your Windows hosts file: this is c:\windows\system32\drivers\etc\hosts 74.208.105.171 gs.apple.com 74.208.10.249 gs.apple.com 2. Download your ipsw file. (Mine was iPad 1 4.2.1) 3. Go to Tinyumbrella and download their Fixrecovery file. (2 are provided 4.2.1 and 4.3 use according to the OS you downloaded from IPSW step 2) 4. Run the device in DFU mode and run the Fixrecovery. 5. Open iTunes and place your device in restore mode (Hold Home buton and power together for abou 20 to 30 seconds) 6. Hold Shift key and click on Restore. Search for your ipsw file you downloaded and sit back and wait till it finishes. Youll experience 16xx errors use iREB and than Open iTunes and Hold Shift key and click on Restore search youtube for videos on how is done
