Jailbreak iPhone, iPod Touch, iPad

Today the Chronic Dev-Team released their jailbreak utility called Greenpois0n. There are currently two versions – for Windows and for Linux users. The team is working on a Mac version, so it will be released soon. Greenpois0n supports only firmware iOS 4.1, so use Limera1n if you want to jailbreak iOS 4.0, iOS 4.0.1 or iOS 4.0.2.

Remember: Do not update to iOS 4.1 if you need the unlock. Ultrasn0w does not support that baseband yet.

Hackers used the bootrom exploit found by Geohot and used in limera1n.

This release of greenpois0n supports:
- iPhone 4
- iPhone 3G S
- iPod touch (4th Generation)
- iPod touch (3rd Generation)
- iPad

Soon there will be another release, adding things like support for:
- Apple TV (2nd Generation)
- iPod touch (2nd Generation)

You can download GreenPois0n from here.

Hacker MuscleNerd has tweeted that the DevTeam plans to release PwnageTool for iOS 4.1 in several days.

For AppleTV 2G users, the goal is for PwnageTool to cover you by Funday/Sunday (but still very limited app capability)

This release should also bring jailbreak for iPod touch and iPad Mac users.

PwnageTool is a Mac OS X jailbreak tool. One of it’s advantages is the ability to preserve old baseband, which means you can have firmware iOS 4.1 with baseband from iOS 4.0 (if you haven’t updated to 4.1 already). And this brings unlcok, because iOS 4.0 is unlockable.

These are instructions on how to jailbreak your iPhone 3GS (all bootroms) and iPhone 4 using Limera1n for Windows. Limera1n supports iOS 4.0, iOS 4.0.1, iOS 4.0.2 and iOS 4.1.

Remember: Do not update to iOS 4.1 if you need the unlock. Ultrasn0w does not support that baseband yet.

Step 1
Download LimeRa1n here. If you have problems downloading go directly to www.limera1n.com and use link at the bottom of the screen.

When prompted save the download to your desktop

Step 2
Double click the limera1n.exe file from the desktop to launch the application

Step 3
Click the large make it ra1n button

Step 4
You iPhone will now be placed in recovery mode.

Follow instructions:

Press both the power and the home buttons.

When Limera1n asks you to, release the power button.

Your phone will now be in DFU mode

As limera1n performs its exploit you will see the image of a lime raindrop on your iPhone.

Limera1n will let you know when it is complete.

Step 5
After you power back on your iPhone you will see a new icon on the SpringBoard entitled limera1n. Press it to continue.

Step 6
Once Limera1n opens select Cydia then press the Install button at the top right of the screen.

Step 7
Once the Cydia installation has completed you must reboot your iPhone.

Step 8
When your iPhone has restarted you can run Cydia. Let it do all the necessary updates

NOTE*: To remove the limera1n icon from your desktop you can install CyDelete from Cydia then use it to delete the application as you delete regular AppStore apps.

UPdate: To have access to the root file system of your iPhone (via file managers like iFunBox) install application called afc2add in Cydia.

Chronic Dev-Team member Joshua Hill has just confirmed that the new Greenpois0n jailbreak, which will allow you to jailbreak Apple’s latest iOS 4.1 software, is expected to be released this Sunday. To make the event more special, Dev-Team has decided to launch the tool at 10 past 10 AM on October 10th 2010. They will be releasing multiple tools, some of which will help you update to 4.1 without losing the possibility of unlocking your baseband for other carriers.

According to the latest tweets from different hackers (MuscleNerd, pod2g and others) the exploit for iOS 4.1 has been already discovered:

Works on 4.1 (!) iBSS iv=c2c5416472e5a0d6f0a25a123d5a2b1c key=1fbc7dcafaec21a150a51eb0eb99367550e24a077b128831b28c065e61f894a0

I just successfully updated to 4.1 without a baseband update. PLEASE wait for 4.1.0 TinyUmbrella!!!

Crazy timing that @pod2g got latest exploit just as 4.1 went public (lots of work left…keep away from 4.1 for now!)

congrats to @pod2g for the latest exploit and also @p0sixninja who have been trying for months.

This means that the jailbreak and unlock for iPhone and iPod Touch is possible. However please be patient and wait for the utilities.

Here’s what hackers tweeted about new Apple firmwares 4.0.1 for iPhones and 3.1.2 for iPad:

DevTeam:

As with *any* new FW, jailbreakers + unlockers must avoid this upcoming 4.1 update until our tools are updated

3GS, ipt3G, iPhone4 users (regardless of current FW or JB status) should backup 4..0 SHSH blobs http://is.gd/dskh9 soon

MuscleNerd:

Obviously avoid today’s 4.0.1 update until JB tools are updated. Luckily, no baseband change so ultrasn0w lives on

each FW version has unique blobs. But using http://is.gd/dskh9 you can get 4.0 blobs on PC while you stay at 3.1.2

Hah for those iPhone3G or ipt2g(non-MC) users at 4.1beta1: use redsn0w from 2 wks ago to JB http://is.gd/dstU3

Comex:

3.2.1 and 4.0.1 out. if you want an unlock, DO NOT UPDATE. No, the jailbreak is not ready yet.

by the way, there is absolutely no reason to update to 4.0.1. it only improves the formula for _displaying bars_, not actual signal

Planetbeing:

There’s no baseband update, so signal strength or radio performance cannot have improved.

Hey guys, I recommend any iPhone 4 users who need jailbreak or unlock use http://3.ly/zN58 to back up their SHSHs NOW, and not upgrade.

iH8sn0w:

WARNING: 3.2.1 for the iPad is out. It KiLLS the Spirit Exploit. 4.0.1 is out too (not for the iPad though)

Congratulations to all iPhone users. iPhone 4 has been successfully jailbroken. iPhone hackers @planetbeing and @chpwn has managed to get root access on the device using @comex’s userland jailbreak method. However do not expect new jailbreak utility soon. @p0sixninja has confirmed that it cant be released in its current shape because it contains some of Apple’s proprietary code:

@i_Enthusiast the jailbreak shown is a more of a stepping stone for us, it can’t be released because it includes some of apples software

You should not expect the carrier unlock soon too. This is because iPhone 4 uses a new baseband OS, which will require a complete rewrite for ultrasn0w unlocking tool:

The DevTeam and others have been checking through the iPhone 4, and have noticed the baseband runs a completely different OS than on previous models. The iPhone 3G and 3G[S] both ran Nucleus OS on the PMB8878 baseband CPU (aka XGold 608), where the iPhone 2G ran the PMB8876 (aka S-Gold 2). iPhone 4 uses the PMB9800, or X-Gold 618 – running a separate OS – ThreadX, an RTOS by ExpressLogic.

Good news from DevTeam. They just announced via twitter that unlock for firmwares 3.1.3 and 4.0 is ready:

RT @MuscleNerd: ultrasn0w tips: 1) Works for all basebands since 3.0 FW 2) Remember to disable 3G on T-Mobile USA

ultrasn0w 0.93 released! Cydia repo is repo666.ultrasn0w.com. Works with basebands 04.26.08 thru 05.13.04

This means, that all users with basebands 04.26.08, 05.11.07, 05.12.01 and 05.13.04 can use ultrasn0w 0.93.

There is no jailbreak for just released iOS4, so you need to wait a bit. Firmware 3.1.3 who need unlock can update ultrasn0w and use their iPhones with any carrier.

Hacker msftguy created unofficial PwnageTool which allows to upgrade to the pre-release of iOS 4.0 GM while keeping your jailbreak and old baseband.

This is not an official release by Devteam, so we recommend to wait for the final versions of both iOS 4.0 and PwnageTool.

For the advanced users who want to experiment here is a link.

Msftguy also provided a video:

Today Apple began selling iPhones without AT&T plan. Apple’s new policy is that anyone can walk into an Apple Store and pick up an iPhone 8GB for $499, 16GB for $599 and 32GB for $699. They allow one unit per customer per day, up to 10 iPhones.

The iPhones are still locked to AT&T’s network. Of course, these devices will be sold with the latest baseband which is not yet unlockable; however, you can use RedSn0w to perform a tethered jailbreak.
