Jailbreak iPhone, iPod Touch, iPad

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

Vooma announced a new case for iPhone that includes a backup battery and a slot for SIM-card. The case can work with the app on jailbroken iPhone that emulates the native phone app to make calls via the external SIM card.

John Biggs from TechCrunch tried a pre-release case and noted that all the main functionality remains the same in the Vooma app, but its look and feel is somewhat different. For example, its dialer is a bitmapped copy of the native dialer screen and number and letters look slightly warped.

There are no much details, however it appears that the case works with mini-SIM cards, instead of micro-SIM cards used in the iPhone 4S and iPhone 4. In addition, external SIM card can be used only for voice calls and data is likely to go through the SIM installed in the iPhone. Since the external SIM card works with its own app the iPhone’s SIM card can still be used for making voice calls even when the case is installed.

This case would be helpful for international travelers wanting to use a prepaid SIM from a local mobile carrier, without need to unlock their subsidized smartphone. To unlock an iPhone is usually more difficult than to simply jailbreak it. Vooma’s homopage offers a sign-up form to receive more information on its Peel PG920 case, but the company has yet provided no details on its availability or pricing.

The iPhone Dev-Team has updated RedSn0w with support for jailbreaking iOS 5.0.1 beta which was recently released for iOS developers.

RedSn0w 0.9.9b8 recognizes 5.0.1 beta and you don’t have to “point at 5.0 IPSW” any more. Since the IPSW isn’t public, you’ll still need to provide it once to redsn0w (Extra -> Select IPSW).

Mac users can also create custom firmware and preserve baseband for unlock. However ultrasn0w doesn’t get updated for betas yet.

This is still a tethered jailbreak for all except old-bootrom 3GS users.

You can download RedSn0w from here.

UPDATE: to jailbreak ioS 5.0.1 beta 2, just point to iOS 5 or iOS 5.0.1 IPSW

Iinstructions how to change tethered iOS 5 jailbreak to a semi tethered jailbreak are available here.

iOS 5 is currently jailbreakable using redsn0w 0.9.9b5 or sn0wbreeze 2.8b8. So developers are working hard to update their apps and tweaks to work with iOS 5. Here is a useful spreadsheet, where you can find information, whether or not your favorite Cydia tweak or app is compatible with iOS 5:

The iPhone Dev-Team has released an update to their UltraSn0w unlock bringing support for iOS 5. Remember that NO new basebands are supported in this release. It only adds support for iOS 5 with old basebands.

Here is the list of supported basebands:

• iPhone 4: 01.59.00
• iPhone 3G/3GS: 04.26.08, 05.11.07, 05.12.01, 05.13.04, 06.15.00.

If have one of the above baseband version and need unlock you can upgrade to iOS 5 without updating your baseband using RedSn0w 0.9.9b5.

Ultrasn0w 1.2.4 is available in Cydia.

We’ve updated ultrasn0w to be compatible with iOS5, which came out a few days ago. While ultrasn0w 1.2.4 (available now in Cydia) doesn’t add support for any new basebands, the update is required for any ultrasn0w unlockers trying out iOS5 (it remains backwards compatible though, so you should be able to use it no matter what firmware you have).

The supported basebands for the iPhone 3G and 3GS are 04.26.08, 05.11.07, 05.12.01, 05.13.04, and 06.15.00. The baseband supported for the iPhone4 is 01.59.00.

Remember, the only way to get to iOS5 while preserving your ultrasn0w-compatible baseband is by using a custom IPSW. redsn0w now has the ability to create such a custom IPSW for you (at least on Macs…the same capability for Windows will be coming soon).

The majority of people who use ultrasn0w at iOS5 right now will probably be those with old-bootrom iPhone3GS devices, since they already have an untethered jailbreak via redsn0w. For everyone else, the iOS5 jailbreak is currently tethered and you need to “Just boot” tethered with redsn0w every time your phone reboots. That’s not always easy to do if your phone reboots while away from home!

Note: there’s a special “trick” that iPhone3GS owners with baseband 06.15 need for iOS5. During the new setup screens you see when you start iOS5 for the first time, you’ll be asked about Location Services. Be sure to select “Disable Location Services” when asked! Later on in the setup, you’ll have the chance to turn on Location Services again when asked if you want to use “Find my iPhone”. It’s fine to turn it back on at that point, if that’s your desire (or you can always go in and enable it in Settings.app).

Also, some iPhone3GS users with the 06.15 baseband may have tried to install iOS5 using a stock IPSW (even though you should never ever try to use a stock IPSW if you’re an ultrasn0w unlocker). If you did try this, your baseband is probably in an inconsistent state, and you’ll need to reflash the 06.15 baseband again (using redsn0w). Be very careful if you use redsn0w to reflash the iPad baseband — don’t interrupt the process! And please avoid using stock IPSWs in the future Unlockers should never go near stock IPSWs.

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

Hackers from the Chronic Dev Team recently announced that they have found 5 userland exploits in iOS 5. To us this means that it is very likely that an untethered jailbreak will be available for the upcoming firmware release.

P0sixninja made the announcement at MyGreatFest jailbreak conference held in London, England.

While this is a “record breaking number of exploits found”, userland exploits can be easily fixed via a minor software update. The exploits are kept in secret, so hopefully Apple won’t fix them before the expected iOS 5 launch next month.

The jailbreak is expected for all devices, including iPhone 3GS, iPhone 4, iPad, iPad 2, iPod Touch and even future iPhone 4S and iPhone 5.

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.
