Jailbreak iPhone, iPod Touch, iPad

Untethered jailbreak is available for iOS 5.0.1 firmware on iPhone3GS, iPhone4, iPhone4-CDMA, iPad1, iPod touch 3G, iPod touch 4G.

1. If you’re already on iOS 5.0.1 with a tethered jailbreak, you have two even choices:

1. Run redsn0w 0.9.10 over your current jailbreak (deselect “Install Cydia”)
2. Install the Cydia package prepared by the chronic devteam. It is called Corona 5.0.1 Untether. (tutorial)

2. If you are not on 5.0.1 yet, update now! If you unlock via ultrasn0w or gevey, make sure you update to 5.0.1 via a custom IPSW! See our guides for sn0wbreeze here. Once you’re at 5.0.1, use the latest redsn0w 0.9.10 to both jailbreak and untether.

You can download RedSn0w 0.9.10b1 here.

Our step-by-step tutorials for untethered jailbreak using redsn0w 0.9.10:

• iPhone 4
• iPhone 3GS
• iPod Touch 4G
• iPod Touch 3G
• iPad 1

iPhone Dev-Team released RedSn0w 0.9.9b9 with full iOS 5.0.1 support (no need to point to iOS 5.0 any more). New version also features support for SHSH and APTickets:

• native support for 5.0.1 (no need to point redsn0w at 5.0 IPSW or use command-line args).  Support automatically extends to all of redsn0w’s various functions: “Jailbreak”, “Just boot”, “Fetch blobs”, “Stitch blobs”, “Recovery Fix”
• iBooks fixed in 5.0 and 5.0.1.  This is a targeted fix that doesn’t remove entire sandbox mechanism.  5.x users already using redsn0w “Just Boot” can just use the new version without redoing entire jailbreak again
• 3GS old-bootrom owners can now create custom IPSWs without blobs
• ultrasn0w compatability update (i.e. same baseband requirements) for 5.0.1 will be available on Cydia Monday
• support for newer 8GB iPhone4 (which until now had problems with “Fetch blobs”).  Thanks to @JKjeepnJeff for loaning us one of these newer i4 units for testing!
• allows Windows users (not just OS X users) to use the “Custom” button to create IPSWs without baseband updates.  (Update: please wait for 0.9.9b9b for this!)
• accommodates APTickets in 5.x (until next Apple countermove).  APTickets are crypto-verified before submitting to Cydia, just like the main blobs.  Cydia server support for sending back the APTickets is upcoming.  For now, use stitched IPSWs for 5.x.  Due to APTickets, stitched 5.x IPSWs now require user to start in “Pwned DFU” mode
• Support added for stitching 4.x blobs to iPad2-GSM IPSWs.  Similar to @notcom’s TinyCFW but doesn’t require lots of RAM or a TSS-assisted restore. Won’t work for iPad2 5.x blobs (or iPhone4S at all) until a bootrom-level exploit is out
• top line now shows whether (and where) a redsn0w update is available, or if the version being run is the latest.  Uses DNS TXT record to alleviate any concerns about snooping
• no 5.1 beta support at this time (major apps like Cydia are not yet compatible)
• @pod2g has been doing a great job porting his 5.x untether…check his blog for updates!
• Owners of newer 3GS iPhones must not flash the iPad baseband.  The iPad baseband will not work on 3GS iPhones built later than 2011 week 35.  You have a week 35 or later device if your serial # starts with xx135.

Update #17b: Version 0.9.9b9b enables the “Custom” button for Windows users, and make the 3GS week 35 warning a more explicit part of the process.

You can download RedSn0w 0.9.9b9b here.

UPDATE: redsn0w updated to redsn0w 0.9.9b9d.

Pod2g has recently announced that he has successfully performed an untethered jailbreak on an iPhone 4 running iOS 5.0.1.

Got an untethered iPhone 4 running iOS 5.0.1. Feel free to update.

Of course, if you want to SIM unlock, don’t update using Apple’s original FW nor update OTA.

This means jailbreakers can update to iOS 5.0.1. Previously it was recommended to stay on iOS 5. Unlockers as usual should stay away from Apple’s firmwares and from iOS 5.0.1.

We strongly recommend that everyone use TinyUmbrella to save their iOS 5.0.1 SHSH Blobs.

Pod2g writes in his blog, that next devices he will try to untehter jailbreak are iPod 3G, iPod 4G and iPad 1.

Apple has recently released iOS 5.0.1. It is still tethered jailbreakable. However if you want untethered jailbreak or unlock – you should stay away from 5.0.1

Earlier this week pod2g reported that a code signing bug found in iOS 5.0 will make it easier for hackers to develop a full jailbreak for iOS 5 firmware version. That bug might have been closed in iOS 5.0.1. UPDATE: According to pod2g the bug is still present, but harder to exploit because another exploit found by Charlie Miller is fixed in iOS 5.0.1.

Also, MuscleNerd via twitter has warned iOS users that there is no downgrade from iOS 5.0.1 to iOS 5.0 yet and he recommends to wait until downgrade mechanism is available.

Jailbreakers and unlockers should avoid today’s 5.0.1 until a flow for downgrading to 5.0 is developed.

Downgrade flow needs to be modified for AP “nonce” http://is.gd/b3G0io … saved SHSH blobs are not enough to downgrade to 5.0

UPDATE: Apple latest firmware is iOS 5.1.1. Apple has stopped signing all other firmwares, including iOS 5.0.1, iOS 4.3.3 and iOS 4.3.5. This means you can NOT restore to 5.0.1/4.3.3/4.3.5 any more (both original and custom), unless you have saved your SHSH keys for it.

If you have decided to perform an untethered jailbreak and unlock, you need to get the following information:

1. What type of device do you have (iPhone 3G/3GS/4, iPod Touch 3G/4G, iPad 1/2, Apple TV)?
2. Do you need unlock (if your iPhone locked to one carrier and you want to use it with another)?
   The answer is NO, if the device is not iPhone, if it was purchased as factory unlocked and can be used with any cellular carrier (f.e. in Canada, France, etc).
   If the answer is YES, you need to find out your modem version (Setting-General-About-Modem).
3. What firmware version do you have? Take a look at Setting-General-About-Version. For example it could be iOS 4.3.3.
4. What operating system do you use on your desktop (Windows, Mac OS)?

How to perform jailbreak, when you do NOT need an unlock

For iPhone 3G the latest is iOS 4.2.1. You can perform jailbreak with any utility. For iOS 4.2.1 you can also use them or GreenPois0n (Windows, Mac OS).

iPad 2 jailbreak is available only for iOS 4.3.3 via JailbreakMe and and iOS 5.0.1 via Absenthe.

iPhone 4S jailbreak is available for iOS 5.0 / iOS 5.0.1 via Absenthe.

iOS 4.3.3

Apple stopped signing iOS 4.3.3, so you cannot update to iOS 4.3.3 without SHSH keys saved (in advance some time ago). If you have iPhone 4, iPhone 3GS, iPad 1, iPod Touch 3G or iPod Touch 4G that run iOS 4.3.3 – use JailbreakMe or RedSn0w to untether jailbreak your device.

If you have saved SHSH keys for iOS 4.3.3 you can use PwnageTool (Mac OS) or Sn0wBreeze (Windows).

iOS 4.3.4/4.3.5

For iOS 4.3.4/4.3.5 only tethered jailbreak is possible with redsn0w. Tethered means that each time you restart your device you will have to connect it to a computer and run redsn0w. The untethered iOS 4.3.5 jailbreak is possible only for iPhone 3GS with old bootrom. You can detect your bootrom version using this tutorial.

iOS 5

To jailbreak and unlock iOS 5 use latest version of redsn0w 0.9.9 or sn0wbreeze 2.8. You can jailbreak tethered or semi-tethered.

The untethered iOS 5 jailbreak is possible only for iPhone 3GS with old bootrom. You can detect your bootrom version using this tutorial.

iOS 5.0.1

For iPhone 4/3GS, iPad 1, iPod Touch 3G/4G an untethered jailbreak is available for iOS 5.0.1. For untethered jailbreak use the latest redsn0w 0.9.10 or Corona – package from Cydia to untether currently installed tethered jailbreak.

Tutorial how to untether installed tethered jailbreak is available here.

For iPhone 4S and iPad 2 use Absenthe.

For tethered iOS 5.0.1 jailbreak you an use redsn0w 0.9.9 and sn0wbreeze 2.8.

iOS 5.1 / iOS 5.1.1

For now only tethered jailbreak is available for iPhone 4/3GS, iPad 1 and iPod Touch 3G/4G for iOS 5.1 and iOS 5.1.1.

You can download all firmwares here.

MuscleNerd has announced via Twitter that jailbreak utility RedSn0w 0.9.9b1 is released with major update and numerous new features:

Major improvements and features added to redsn0w 0.9.9b1! See update #9 at http://is.gd/6eek4Y Feedback: @redsn0w_testers

Indeed the list of new features is quite high. There are two main ones:

• There is no need to download firmware any more. There is no need to push Browse IPWS button any more (but you still can).
• Developers added lots of functionality to work with SHSH keys (extract, submit, download, verify, stitch etc)

However this new version does not bring features like untethered jailbreak for iOS 4.3.5 or iOS 5.

Due to some possible bugs we still recommend to use the old RedSn0w 0.9.8b7b, but the new 0.9.9b1 is worth seeing and playing with.

Here are links to our RedSn0w 0.9.8b7b iOS 4.3.5 jailbreak tutorials:

• Mac OS: iPhone 4, iPhone 3GS, iPad 1, iPod Touch 3G, iPod Touch 4G
• Windows: iPhone 4, iPhone 3GS, iPad 1, iPod Touch 3G, iPod Touch 4G

You can download RedSn0w 0.9.9b1 here:

Here is the full list of features from DevTeam:

Update #9: A bunch of new features!

• uses DFU mode to try to automatically determine which device and FW you have
• fetches pieces of public IPSWs from Apple (once).  Non-public IPSWs must be provided manually (once).  It then caches those pieces for future use.
• “Just boot” is a tethered boot.  Uses whatever “Preferences” you’ve set for boot logo and kernel boot-args
• “Pwned DFU” puts your device in a pwned DFU state for some of the iTunes stuff detailed below
• “Recovery fix” gets past 1015 types of errors (when baseband portion of restore fails).  Should work on iOS5 beta too
• “Select IPSW” is for picking non-public IPSWs, or overriding auto-detection
• “SHSH blobs” has a bunch of options…
  • “Fetch” – fetch current PARTIAL blobs on device.  Should complete in under 10 or 15 seconds.  Puts the set of PARTIAL of blobs on your computer as a plist.  Checks if Cydia already has a full set for this device and build.  If not, it submits this PARTIAL set and returns Cydia’s acknowledgement or rejection
  • “Verify”  – cryptographically verifies existing blob files from either redsn0w, TinyUmbrella, or Cydia server.  You can select a whole bunch of blobs to verify at once if you want (like the TinyUmbrella directory)
  • “Submit”  – both verifies and submits one or more blob files to Cydia.  This lets you copy your entire TinyUmbrella cache of blobs up to the Cydia server
  • “Query” - queries the Cydia server for all available FULL or PARTIAL blobs for a given set of ECIDs
  • “Stitch” – stitches either FULL or PARTIAL blobs to a STOCK or CUSTOM IPSW

1. Stitching is NOT yet supported on iPhones! Need to work out the baseband part of the restore process.
2. FULL blobs stitched to a STOCK IPSW gives you a completely self-contained signed IPSW that iTunes will accept without any tricks (no need to go into pwned DFU mode, no need to start TinyUmbrella TSS server, no need to redirect to Cydia server for blobs)
3. PARTIAL blobs stitched to any IPSW requires you to go into pwned DFU mode before running iTunes.  No need to start TU or use Cydia though.
4. Stitching either FULL or PARTIAL blobs to a CUSTOM IPSW also requires a pwned DFU start before iTunes restores.  No need to start TU or use Cydia though./li>
5. Will eventually support fetching the blobs directly from Cydia instead of a file on your computer

MuscleNerd, hacker from DevTeam, has announced via Twitter that a major update to RedSn0w is coming soon.

There will be no need to select an IPSW. Rather than requiring ipsw selection, RedSn0w will now automatically fetch the important pieces directly from Apple (and caches them so that it never needs to re-fetch them again). New version also brings the ability to save and submit SHSH Blobs to Cydia.

Will be pushing out a major redsn0w feature upgrade before my trip to Korea: http://is.gd/PMAdT1 (and look, no IPSW selection button!)

The new version of RedSn0w is expected to be released on Monday.

Check out the screenshots below:

The iPhone Dev-Team has released RedSn0w 0.9.8b3 which can perform a tethered jailbreak on iOS 4.3.4. This means that you will have to connect your device to a computer and run redsn0w each time you restart.

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 your jailbreak!

This jailbreak works with iPhone 3GS, iPhone 4, iPad 1, iPod Touch 3G and iPod Touch 4G. It does not work with iPad 2.

You can download RedSn0w 0.9.8b3 from here: (Mac, Windows)

Famous iPhone hacker Stefan Esser, also known as i0n1c, recently wrote on twitter that we should not expect untether jailbreak for iOS 4.3.4 anytime soon. i0n1c was the one who created untether for iOS 4.3.3 firmware.

Our advice is simple – save your 4.3.3 SHSH keys asap. With these SHSH keys you will be able to restore to iOS 4.3.3 anytime, without – only iOS 4.3.4. Here are tutorials for you.

• How to Save Your SHSH Blobs Mac
• How to Save Your SHSH Blobs Windows

Apple today released iOS 4.3.4 to block the recent jailbreak released by comex. Do not update if you want to remain jailbroken.

Apple will soon stop signing iOS 4.3.3 so please save your SHSH blobs as soon as possible. We have step-by-step tutorials for you:
