Apple released iOS 4.3.3 just a few days ago and they didn’t fix the Untethered exploit we used on 4.3.2 so we quickly have working untethered Jailbreak. All the download links and a written guide are inside the post on how to jailbreak 4.3.3.

4.3.3 Firmware      Mirror

Redsn0w 0.9.8b5:

NOTES:
- This works with iPhone 4(GSM/AT&T), iPhone 3GS, iPod Touch 4G, iPod Touch 3G, and iPad 1
- This DOESN’T work with iPhone 4(verizon) and iPad 2
- On Windows make sure to right click on Redsnow.exe and run it in Windows XP SP3 Compatibility Mode and as Administrator.
- Ultrasn0w unlockers must stay away from redsn0w!
- Update your device to iOS 4.3.3 before you do this guide.
- Update iTunes to the latest version before you do this guide.
Guide:

Step 1: Download Redsn0w for your computer and the 4.3.3 firmware for your device. To make it easy to find save them both to the desktop on your computer.








Step 2: Unzip the Redsn0w file by double clicking on it. Now open the Redsn0w folder and find the Redsn0w app, click on it and open it up.







Step 3: In Redsn0w click the browse button. You will then be prompted to select the 4.3.3 firmware that you saved to your desktop earlier. Be patient and let Redsn0w do its thang’.







Step 4: Once Redsn0w is done click next until it looks like the image above. Go ahead and make sure only “Install Cydia” is check and then click next.


Step 5: Now its time to put your device in DFU mode. The video guide may explain this a little better so make sure you watch it. When you click the next button it will immediately give you instructions to do this go over this quickly. You first need to turn plug your device into your computer via USB, close iTunes and turn your device off. Once you click the next button you will need to hold the power button in for 3 seconds, and then press in the home button while still holding the power for 10 more seconds, and then release the power button while continuing to hold the home button for 30 more seconds. It will count down with you, which is hard to time correctly because it starts right after hitting the next button. If done correctly you should have a device in DFU mode and it should begin the jailbreak process.

Step 6: Slide to unlock, open the Cydia app on your device and there you go! JAILBROKEN!

Jailbreak 4.3.5 Firmware iPhone 4, 3Gs, iPod Touch 4

 Redsn0w iOS5beta

WWDC 2011 is winding down to a close, and developers of jailbroken apps for Cydia are probably itching to get started on all the iOS 5 goodness.  It seems like a good time to release the tethered redsn0w jailbreak for iOS 5. The following devices are supported:

• iPod touch 3G


• iPod touch 4G


• iPad 1


• iPhone3GS


• iPhone4 (GSM)


• iPhone4 (CDMA)

UNLOCKERS AND THOSE PRESERVING THEIR UNLOCKABLE BASEBANDS SHOULD STAY FAR AWAY FROM THIS!  You will very likely lose your unlockable baseband if you try to install iOS 5.


THIS JAILBREAK IS INTENDED ONLY FOR DEVELOPERS OF JAILBROKEN APPS!  There are just too many broken components (Apple’s official apps, 3rd-party App Store apps, Cydia apps, MobileSubstrate apps, etc) for this to be useful to anyone but those truly looking to fix bugs in their iOS 5 jailbroken apps.  (Seriously!)

THIS REDSN0W WILL NOT HACTIVATE!  You need to be an iOS developer with a registered UDID to get past all the new activation screens.  PLEASE DON’T PIRATE APPLE SOFTWARE!  Only registered devs with Macs can develop iOS applications, and only those people will have legitimate access to the beta IPSWs. See update #1 below.

THIS IS A TETHERED JAILBREAK ONLY!  No new exploits are being exposed with this jailbreak (it uses geohot’s limera1n bootrom exploit), but that comes at a cost.  You will need to use redsn0w to “Just boot tethered now”  to be able to use many things, including Cydia and Safari.  If you see a white icon for Cydia, or if Cydia or Safari crash when you open them, it’s because you didn’t boot tethered.

IF YOU HAVE THE 06.15 BASEBAND ON YOUR 3GS…this redsn0w will get you past the iTunes restore error you’ll get when using the stock IPSW (nobody other than those with the 06.15 baseband should be going anywhere near the stock IPSW!).
The way redsn0w works, you will very likely be able to use this on upcoming iOS5 betas, just by continuing to point redsn0w at the 5.0b1 5.0b4 IPSW.  So keep that IPSW handy!
Although most people just launch redsn0w by double-clicking it, remember there are “advanced” options available to those who invoke it from the Terminal shell:

---

Update #1: Since Apple now provides Windows iTunes 10.5 for iOS5 and iCloud developers, it’s no longer the case that only Mac owners can legitimately activate their devices.  We now provide a Windows version of redsn0w for those developers (only!).

Update #2: We’ve updated redsn0w to account for the sandbox changes that affected App Store apps in 5.0b3 (and it now recognizes the IPSWs for all three betas so far).  If you already jailbroke 5.0b3 using the previous redsn0w, you don’t need to re-jailbreak…just use this updated version to boot tethered.  Point redsn0w b3 at the b3 IPSW when jailbreaking iOS5b3.

Update #3: For the convenience of kernel hackers like @comex and @i0n1c, we have a new redsn0w 0.9.8b3 that supports a TETHERED jailbreak for iOS 4.3.4 on all devices that have 4.3.4 except the iPad2.   
The vast majority of people will want to stay back at 4.3.3 because that’s where the untethered jailbreak is!  There are no new features in 4.3.4 — only fixes for jailbreak exploits.
Also, this is a good time to remind everyone (since we’re still seeing confusion about this):  

iPad2 owners with a baseband (3G or CDMA) cannot currently use saved blobs to go back to 4.3.3 once the signing window is closed.  This is unlike every other device, so don’t be confused!  iPad2 owners with basebands should stay away from all updates to maintain the jailbreak!
Update #4:  In conjunction with iOS5 beta4 being released to iOS developers, redsn0w 0.9.8b4 is now available for jailbreak app developers (point the b4 redsn0w at the b4 IPSW).  Remember, it’s a tethered jailbreak right now so you’ll need to use redsn0w to boot into a jailbroken state at each power cycle.

NOTE: It appears that by design, the OTA update that became available starting with iOS 5 beta4 will *not* be automatically applied to jailbroken devices.  That’s a relief to those who don’t want to lose their jailbreak via OTA pushes.  If you’re jailbroken, you’ll need to use the standard iTunes method to get to iOS 5 beta4.

Update #5: redsn0w has been updated to 0.9.8b5, adding support for Apple’s new iOS5 beta5 (point it directly at the beta5 IPSW). Please use this only if you’re a jailbreak app developer with a legit Apple dev account, and remember it’s a tethered jailbreak for now!

Apple’s support document details the technical fixes:

Impact: Viewing a maliciously crafted PDF file may lead to an unexpected application termination or arbitrary code execution
Description: A buffer overflow exists in FreeType’s handling of TrueType fonts. Viewing a maliciously crafted PDF file may lead to an unexpected application termination or arbitrary code execution.

For those who don’t know, PDF vulnerability was used by Comex in his JailbreakMe 3.0 to jailbreak iOS 4.3.3 on iPod Touch 4G, 3G, iPhone 4, 3GS and iPad 2, iPad 1.

ATTENTION: Jailbreakers/unlockers must stay away from iOS 4.3.4 if they want to keep Cydia and other installed jailbreak tweaks.
