Jailbreak iPhone, iPod Touch, iPad

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.

Chronic Dev Team is almost done with a much anticipated untethered jailbreak for iOS 5 and iOS 5.0.1. Team member and French hacker pod2g just released a video showing off the jailbreak. It looks to be near-complete and functioning properly. Take a look:

pod2g even created a blog, where he plans to post the most recent news about his progress:

Today I succeed in jailbreaking my iPod 3G. The exploit is user-land, rely on a user ROP payload and a kernel write anywhere exploit.

I can’t give much details right now, but here are the next steps :
- upgrade the iPod 3G to iOS 5.0.1
- do the same on iPhone 4 / iOS 5.0.1
- then iPad 1 & iPod 4G

At every step, the exploit code needs certainly to be reworked, but I really don’t know right now. Next, I’ll return to the research for iPad 2 and iPhone 4S. I don’t know if I gonna release first for other devices or not. I’ve to think about it. Feel free to give your opinion.

Semi-tethered jailbreak is already available for some devices for both iOS 5 and iOS 5.0.1. But we all want untethered jailbreak and we want jailbreak for iPad 2 and iPhone 4S. So why not help hackers to find new exploits and vulnerabilities?

The Chronic Dev-Team has a released a tool to collect crash reports from iOS devices in order to find vulnerabilities that could lead to an untethered jailbreak.

The idea is very simple. When your iPhone, iPad or iPod Touch crashes it sends data to Apple (you can turn it this off though). Apple uses these reports to update iOS in the future. By the way, it also uses them to fix exploits found by jailbreakers. P0sixninja says that Apple closed several exploits they have found in IOS 5 beta before the final version of the software was released.

In order to find more vulnerabilities as fast as possible, the team has developed a tool which will copy the crash reports from your device and analyze them to locate potential exploits. The tool will also remove the crash reports from your device and modify your iTunes installation to prevent uploading of that diagnostic information to Apple.

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

iPhone 3GS jailbreak can be either tethered or untethered. Tethered jailbreak means that each time you restart your device you will need to connect it to a computer and run redsn0w. If you have iPhone 3GS with an old bootrom version 359.3, the jailbreak is untethered. If your device has bootrom version 359.3.2 and higher, iOS 5/4.3.5 jailbreak will be tethered.

You can read tutorial to detect if your iPhone 3GS has new or old bootrom version here.

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.

Here are our step-by-step tutorials that will guide you through all the process of jailbreaking iOS 5 with redsn0w 0.9.9 and sn0wbreeze 2.8:

iPhone 4

Semi-Tethered jailbreak iOS 5:

• RedSn0w (Windows)
• RedSn0w (Mac OS)
• Sn0wBreeze (Windows)

The iPhone Dev-Team released jailbreak utility RedSn0w 0.9.9b6 for both Windows and Mac users. The new version offers full iOS 5 jailbreak support for Windows and fixes Location Services issue for iPhone 3GS devices running the 06.15 baseband. This is still a tethered jailbreak for iPhone 4, iPhone 3GS, iPad 1, iPod Touch 3G and iPod Touch 4G:

We’ve released version 0.9.9b6 of redsn0w, with both a functional fix and cosmetic fix for iOS5 jailbreakers. For iPhone3GS owners with the 06.15 baseband, this redsn0w eliminates the network crash you saw when using Location Services in iOS5 (in fact, you don’t even need to disable Location Services anymore during the initial setup). The cosmetic fix is to the visual countdown you see when going into DFU mode.

It’s okay to re-run this redsn0w over an existing device jailbroken at iOS5. Just choose “Jailbreak” again and de-select Cydia (in other words, all the checkboxes will be unchecked). If you are lucky enough to have an old-bootrom iPhone3GS, please pre-select the IPSW first (redsn0w can’t yet auto-detect the FW version of your old-bootrom 3GS if it’s already been jailbroken).

Just as redsnow 0.9.9b5 the new version supports creating custom firmwares with preserving baseband (modem) version for unlock. Unfortunately right now custom firmware functionality works only with Mac version.

You can download the latest RedSn0w version here.

UPDATE:
Here are links to our RedSn0w 0.9.9 iOS 5 jailbreak tutorials:

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

If for some reason you don’t want to use redsn0w 0.9.9 to jailbreak your iOS 5, here is a good alternative utility – Sn0wBreeze 2.8b8. It can perform a tethered jailbreak for iPhone 3GS, iPhone 4, iPad 1, iPod Touch 3G and iPod Touch 4G.

As usual it will preserve your baseband (modem) version for unlock with ultrasn0w 1.2.4 or Gevey Sim.

You can download Sn0wBreeze 2.8b8 here.

UPDATE: Sn0wBreeze 2.8b8 step-by-step jailbreak and unlock tutorials:

• iPhone 4 - Sn0wBreeze (Windows)
• iPhone 3GS - Sn0wBreeze (Windows)
