These are instructions on how to jailbreak your iPhone 4 and iPhone 3GS on iOS 4.3.3 or iOS 4.2.8 (Verizon CDMA) using JailbreakMe.

If you are already on iOS 4.3.3 or iOS 4.2.8 you can skip the first five steps of this tutorial.

*Remember that updating to iOS 4.3.3 will update your baseband and perhaps ruin your chances of an unlock. Use TinyUmbrella (Mac, Windows) to update the iPhone 4 to iOS 4.3.3 without updating the baseband.

Step One
Create a Pwnage folder on your desktop and place the iOS 4.3.3 or iOS 4.2.8 (Verizon CDMA) ipsw in it.

You can download the ipsw for your device from here:
4.3.3 (3GS): iPhone2,1_4.3.3_8J2_Restore.ipsw
4.3.3 (4 GSM): iPhone3,1_4.3.3_8J2_Restore.ipsw
4.2.8 (4 CDMA): iPhone3,3_4.2.8_8E401_Restore.ipsw

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

Step Three
Select your iPhone from the list of devices on the left

Step Four
Hold down the Option (Mac) or Shift (Windows) key and click the Restore button.

Step Five
Select the iOS 4.3.3 ipsw from the Pwnage folder on your desktop and click Open.

Step Six
Once your iPhone is running iOS 4.3.3, press to launch Safari from your desktop.

Step Seven
Navigate to http://www.jailbreakme.com and press the Free button.

Step Eight
Press the Install button.

Step Nine
Safari will now close and Cydia will download and install.

Step Ten
Press to launch Cydia and enjoy your jailbroken iPhone!

Is there an unlock for iOS 4.3 baseband 4.10.01? Pls help me i've been waiting for this for a while now and i have no idea if its available already or not. Thanks for your answer! :)

Please help: I installed Lion and accidentally had my iPhone 3GS updated to 4.3.4 although it was greenpois0n jailbroken on iPad 6.15.00 baseband. Now it won't let me restore on iTunes, with that annoying 'unknown' error. Any chance I'll be able to use this phone again in the near (distant?) future? Cheers

With the release of iOS 4.3.4, is it still possible to jailbreak my 3GS (currently not running on 4.3.3) with these instruction?

I got my Iphone 4 in December but with no contract, from the US. I gifted it to my brother in Dubai, the problem was that the phone was locked. Finally today I got through Iclarified and I was following the steps and then I came to the part where I had to use safari on the Iphone4 and go to www.jailbreakme.com. i did that and there it said come back on your Iphone, iPad, or IPOD touch to use Jailbreak me. The thing is I was on my Iphone 4 when I did that but still it said that and could not download Cydia. Could someone help please? Thanks.

My Iphone is a 4.3.3 and I want to Jailbreak it first and then Unlock it. So what to do about this note: *Remember that updating to iOS 4.3.3 will update your baseband and perhaps ruin your chances of an unlock. Use TinyUmbrella (Mac, Windows) to update the iPhone 4 to iOS 4.3.3 without updating the baseband.

WORKED LIKE A CHARM THNX FOR A VERY EASY JB!

Marirs - July 9, 2011 at 11:35am

So Why is Step Five (5) Required?

yaman - July 14, 2011 at 3:10pm

If you already have 4.3.3 it says to skip the first five steps not jump to step five.

Hi I already had Cydia threw redsn0w (computer) and I wanted to try it threw iPhone 4's Safari browser. It worked but it didnt let me download FuriousMod to unlock with Gevey Ultra Sim. I wanted to know if its a bug or if there is a way i can download it?

Shinyscot - July 7, 2011 at 9:27pm

I already had 4.3.3 installed, whenever Cydia begins loading it gets as far as install then cancels. No idea whats happening. Anyone have any suggestions?

Martin - July 9, 2011 at 8:02pm

I have the same problem. Was on 4.2 (with greenpoison i think) and then upgraded to 4.3.3 before the jailbreakme "fix". My phone is jailbroken (I can run some applications that were left on the phone) but no cydia. Rather disturbing...

JB - July 7, 2011 at 8:53am

I've been trying to update while having TinyUmbrella running in the background to keep my baseband but I can't get out of DFU mode. I've restored numerous times (Shift+restore etc.) but no dice. What am I doing wrong?

ctj - July 7, 2011 at 12:43pm

use pwnage tool instead

JB - July 8, 2011 at 1:11am

Thanks ctj. I used pwnage tool and redsn0w to get it going. It kept my baseband fine but my contacts, ringtones, music, videos etc. aren't properly syncing from my last backup. Weird. Guess I have to try to figure that out. Thanks again ctj.

fishycrakers - July 18, 2011 at 11:39pm

I couldn't get pass step:1. The ipsw (if its called that), or restore file, was in a Win Rar file and so wouldnt let me restore from it. When I extract the files it still wont let me restore from them

ross - July 6, 2011 at 11:08pm

Are there any battery drain problems with this, i wont know until tommorow!

James - July 6, 2011 at 3:56pm

I love this type of jailbreak great job! I wonder if there is any advantage to using this over pwnage tool or redsn0w (except for the obvious convienence). Still an issue with baseband mismatch requiring ultrasn0w?

Hi i'm updating my iphone 3gs from IOS 4.1 on 4.3.3 and at step 6 when restoring iphone with this file downloaded from your site (iPhone2,1_4.3.3_8J2_Restore) error 1015 appears, what can i do about this!

Manuel - July 6, 2011 at 10:47pm

Just remove the gs.apple.com address redirection in your host file! :) That did the trick for me.
