These are instructions on how to jailbreak your iPhone 3GS on the 4.3.3 firmware using RedSn0w for Windows. The Mac version of this tutorial is here.

Make sure not to update to iOS 4.3.3 if you need an unlock as one is not yet available unless you opt to use the iPad baseband.

During this process you can update your baseband to the 06.15 version. If you are on 05.14 or 05.15 or higher you will need to do this to unlock. You do not need to do this for jailbreak only. Please read the following very carefully before deciding whether to do this. You can find out baseband version here.

1. There is no way to come back down from 06.15, and there’s no hiding the baseband version from Apple. You’ll be voiding your warranty in a very obvious way.
2. If some future baseband comes out with a critical fix, you won’t be able to update to it if it remains down in the 05.xx sequence (then again, you wouldn’t update to it if you wanted to keep your unlock anyway).
3. Starting with FW 4.2.1 if you have 06.15 on your iPhone you won’t ever be able to restore to stock firmware (it will fail). You’ll need to only restore to custom IPSWs (then again, if you’re unlocker you should already be doing that).
4. There are reports that 06.15 may disable your GPS. The iPhone Dev-Team is currently working on a fix.

Don’t update to 06.15 if you don’t need to! Only do this if you need the unlock and you’re stuck on 05.14 or 05.15, and you're willing to assume the above risks. If your baseband is already unlockable and you are on a lower firmware version then use PwnageTool to update to 4.3.3 without upgrading your baseband.

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 4.3.3 firmware from below and place it in the same folder.

4.3.3 (3GS): iPhone2,1_4.3.3_8J2_Restore.ipsw

Extract the RedSn0w zip file into the same folder.

Step Two
Connect your iPhone to the computer and launch iTunes.
How to Jailbreak Your iPhone 3GS Using RedSn0w (Windows) [4.3.3]

Once iTunes has finished updating your iPhone to the desired firmware open the Pwnage folder on your desktop and launch the redsn0w application from the redsn0w folder we extracted earlier.

**Windows 7 users may need to run RedSn0w in Vista compatibility mode. You can do this by right clicking the executable and selecting Properties from the contextual menu

If you read the warning above and you would like to update your baseband to the 06.15 iPad version for unlock then check Install iPad Baseband. Click Yes when prompted to confirm your decision.

*As usual a big thanks to the iPhone Dev-Teams, Geohot, and I0n1c for their hard work and contribution to the iPhone community.
**Windows 7 users can try running RedSn0w as an administrator in Windows Vista or XP compatibility mode if you experience any difficulties.

The last version that is redsn0w 0.9.6rc19 doesnt have an option to select to "upgrade ipad baseband". Also redsn0w 0.9.6rc16 has a option but it cannot fetch the ipad baseband? Any help? My phone is running on 4.3.3 and has baseband 5.16.02. I have to upgrade baseband to 06.15 to unlock.

Hi , I have a 3GS. It was with 4.2.1 I have upgrade to ipad BB to unlock it. Now I have decided to upgrade to 4.3.3 as it is untethered jailbreak. I created a custom firmware using sn0wbreeze and restore via itunes. I got errors like 3128, 600x and finally i got a 1015 error. After this my iphone is always in DFU mode (Black screen). Now if i tried with a 4.2.1 firmware i got the error 28 and if I try with 4.3.3 i am getting 600x error. The phone is always in black screen. If i used the fixrecovery4.3 , it is not doing anything and if i use fixrecovery4.2.1 i got a bright lcd screen and agin it went to black screen. Please let me know ho to solve this?

Hi, I have a 3GS with baseband 5.14 and 4.1 os. I restored to the latest 4.3 as mentioned in the article in iclarified to unlock. However it was asking me to insert a valid sim to activate. I dont have an ATT SIM. I was using this phone just using Wifi and am in a different country. The restore didnt make any mention of having a valid SIM inserted. I was able to restore by following the procedure but not checking the update ipad baseband. Then I used itunes to get the backup file I had created. A few questions: So, once I update to 6.15 baseband, can I still restore using the same backup? Or do I need to store a custom IPSW and if so how do I do it? Can I still unlock if I dont have an ATT sim? thanks kapil
kapil - June 15, 2011 at 1:33pm
Unfortunately I didnt get any direct help. But from reading a some guess work I finally got this unlocked. Followed the above procedure to get jailbroken and cydia first. Then updated the ipad baseband. When updating kept an ATT card inside(got it from a colleague as I am not in US) Its now unlocked. 2 issues: GPS works sometimes. Its not unusable, but not accurate either and sometimes doesnt work. The battery drains very quickly (need to recharge every night)
albertfann - July 1, 2011 at 9:03am
its doesn't need to use ATT sim cards. ato Redsn0w remember chose "install Cydia" & " ipad basemand" it will ulock your iphone, n ipad basemand use for unlock your carrier ( at cydia search ultrasn0w for unlock carrier) hope it will help.
Olavi - May 29, 2011 at 7:52am
If i update through iTunes , does my baseband change? I have iPhone 3GS, 4.0.1 ; baseband 05.13.04

my iphone 3gs was updated to 4.3.3 with baseband 05.16.02, after jailbroken there are no signal for the network, what can i do except changing the baseband to ipad version?
albertfann - July 1, 2011 at 9:05am
you should "install ipad basemand" after that at cydia search "ultrasn0w" to unlock your carrier.

Hi, I have jailbroken and inlocked my iphone 3GS using readsn0w. Now the version is 4.2.1 with baseband 06.15.00. Now can I upgrade the OS version? Please let me know if there are any tutorials.. Regards Siva G

I was able to get it to work. I have a iPhone 3GS updated with 4.3.3 firmware and base band of 05.16.02. If you plan to unlock, you will have to intall the 06.15.00 base band first. I would recommend doing so locally (http://www.beijingiphonerepair.com/hack/fetch-or-download-ipad-baseband-6-15-00-without-internet-connection-local-computer/). After that is complete, then proceed to the jailbreak steps. It took my two weeks to figure it out and 10 minutes to actually jailbreak and unlock the iPhone.
kapil - May 31, 2011 at 12:06am
Hi Ashish, Did you need the ATT SIm card to unlock? Also, if something goes wrong what are the steps to restore your iphone to a working condition even if its still locked?
