PwnageTool 4.3.3, Redsn0w 0.9.6rc15 And Ultrasn0w 1.2.3 Released For iOS 4.3.3

Jailbreak iOS 4 on iPhone 3GS

iPhone Dev team has just released PwnageTool 4.3.3 and Redsn0w 0.9.6rc15 for iOS 4.3.3 that incorporates the untether jailbreak developed by iPhone hacking expert Stefan Esser.

PwnageTool 4.3.3 will allow iPhone users to safely restore to a pre-jailbroken iOS 4.3.3 firmware and retain their current baseband so that they can use Ultrasn0w to unlock their GSM iPhone, which is only useful for users with older baseband.

Dev Team has provided the following information on their blog:

… three in a row!  Apple released iOS 4.3.3 on Wednesday, and once again the untethered jailbreak exploit that@i0n1c created for 4.3.1 still works.  That makes it an unprecedented three firmwares where the same userland exploit works.  We’re not exactly sure why Apple hasn’t fixed the hole yet, but we’re not complaining!

Today’s PwnageTool and redsn0w incorporate @i0n1c’s port to 4.3.3 (it’s ironic that such a long-lasting untether doesn’t even have an official name!).  It also of course uses geohot’s limera1n bootrom exploit to inject the jailbreak.

Some things to note:

  1. ultrasn0w unlockers must stay away from redsn0w!  Use only a custom IPSW to update to 4.3.3, to avoid updating your baseband.
  2. ultrasn0w has been updated to v1.2.3 to be compatible with iOS 4.3.3 and earlier (the ultrasn0w update does not include any new baseband support!). Please reboot your iPhone using the normal “slide to power off” swipe after installing ultrasn0w 1.2.3.
  3. By popular demand, redsn0w now allows you to enable multitasking gestures (although most will find it useful only on iPads).

PwnageTool 4.3.3 and Redsn0w 0.9.6rc15 supports the following iOS devices for iOS 4.3.3:

PwnageTool 4.3.3 and Redsn0w 0.9.6rc15 does not support iPad 2 or iOS 4.2.8. Dev Team has also provided the following update for iPad 2 users:

The iPad2 jailbreak remains under development.  As you may know, the original exploit @comex developed in the first week of the iPad2 release was mysteriously fixed by Apple within days of its development.  Partly because of this, don’t expect much public discussion of the iPad2 jailbreak until it’s actually finished and ready for release (and please avoid asking about it).  In all liklihood, it will be a userland exploit like the first (unreleased) one, not dependent on bootrom dumps.  The first one can’t be released even for those with the original 4.3 firmware due to legal (distribution) reasons.

iPad, iPod Touch and iPhone users who don’t care about unlocking are better off using Redsn0w as one doesn’t need to preserve baseband like iPhone users.

Please note that jailbreaking your iDevice may void its warranty so proceed at your own risk. Please don’t forget to backup your iPhone before you proceed. You can refer to this post for instructions on how to backup your iPhone.

Redns0w 0.9.6rc15 can be downloaded from the following link:

PwnageTool 4.3.3 is available only for Mac users and you can download it from one of the mirror sites:

Ultrasn0w v1.2.3 can be installed on a jailbroken iPhone 4 (baseband 01.59.00) or iPhone 3GS (baseband 04.26.08, 05.11.07, 05.12.01, 05.13.04 and 06.15.00) on iOS 4.3.3. Note: You can find your iPhone’s baseband by going to Settings –> About –> Modem Firmware

Ultrasn0w v1.2.3 can’t unlock iPhone 4 basebands – 02.10.04 (bundled with iOS 4.1), 03.10.01 (bundled with iOS 4.2.1), 04.10.01 (bundled with iOS 4.3) or iPhone 3GS basebands – 05.14.02 (bundled with iOS 4.1), baseband 05.15.04 (bundled with iOS 4.2.1), baseband 05.16.01 (bundled with iOS 4.3) and baseband 05.16.02 (bundled with iOS 4.3.1, iOS 4.3.2).

iPhone users who don’t care about unlocking but want to fix the signal bar issue also need to install Ultrasn0w 1.2.3.

If you meet the baseband requirements then you can follow these steps to unlock your jailbroken iPhone or fix the signal bar issue (T-Mobile USA users should disable 3G before using Ultrasn0w):

  1. Launch Cydia from the homescreen.
  2. Tap on the Search tab and search for ‘ultrasn0w’. That last “o” is actually the number zero “0”. If you use the letter “o” you’ll get an error.
  3. Select ultrasn0w from the search results.
  4. Then tap on the Install button.
  5. Tap on the Confirm button.
  6. You will be prompted to Restart SpringBoard, tap on it.
  7. Reboot your iPhone, your iPhone should now be successfully unlocked or the signal bar issue should be fixed.

As always, let us know how it goes.

  • Deep

    anyone having this issue?, itunes saying “the iphone could not be restored. this device isn’t eligible for the requested build.” (AT&T iphone4 )

    • John

      I got the same problem. I’ve solved it by changing the hosts file back to apple. It was pointing to cydia servers before.

      For me, the following worked (on a mac):
      Go>Go to Folder
      Type in ‘/etc’
      Open the file named hosts in TextEdit
      Remove the line ‘’

      • Deep

        thanks! it works yeeaaa!!!

  • eddie-a

    I hace been having problem with unlocking my iphone 4GS verison: 4.3.3. my modemfirmware is: 05.16.02. as far I know the available modemfireware for this jailbreak is: 01.59.00 / 04.26.08 / 05.11.07 / 05.12.01 / 05.13.04 / 06.15.00. What to do? Please reply

  • Simen


  • Ultrasn0w 1.2.3 does not support baseband 05.16.02. One option would be upgrade to iPad baseband firmware (06.15.00) using but we don’t recommended it as you will end up losing GPS and there is no way to downgrade it currently.

  • problematickid

    Heeeeyy guys, download link of RedSn0w for Windows doesn’t work… need help!

  • lee

    Hello anyone,
    I have 3gs version 4.1 and BB 6.15. Can I use the PawnageToll 4.3.3 to update my version from 4.1 to 4.3.3? Pls any expert reply

  • Justin

    Just tried to JB and unlock my Iphone 4 WITHOUT success. JB seems to work BUT unlock does not. In fact, for some reason I cannot use my Iphone with the SIM that was working BEFORE I JB and/or tried to unlock it. Now it does not work with ANY SIM!! So confused now.

    I JB using redsn0w rc15 with 4.3.3 (baseband 04.10.01). Then ran redsn0w rc16 for the bug fix and also tried ultrasn0w 1.2.3 as well.

    All other functions seem to work and I can use it as an Itouch with WiFi but phone functionality seems to not work at all. Disappointed to say the least and would appreciate any help.

    If it is not appropriate to ask here, could someone point in the right direction on where to go to ask? Probably need to speak to Comex or Dev team and hopefully they will read this.
