Jailbreak iPhone, iPod Touch, iPad

DevTeam worked hard for the last several hours and released jailbreak tool for iOS 4.2.1. It is redsn0w 0.9.6 b4.

As usual we remind all ultrasn0w unlockers please stay away from this official firmware. Wait for the ability to create custom 4.2.1 IPSWs that don’t update your baseband!

New redsn0w 0.9.6 b4 uses limera1n exploit and will successfully jailbreak all devices. The only problem is that it is a tethered jailbreak, which means you will have to plug it to a computer and rerun redsn0w on every reboot. This so called tethered or semi-tethered jailbreak. This condition applies to iPhone 3GS (new bootrom), iPhone 4, iPad, iPod touch 2G (MC model), iPod touch 3G and iPod touch 4G. Hackers are working hard to create untethered jailbreak for these devices. To use future untethered jailbreak you need to save SHSH keys for iOS 4.1 using TinyUmbrella utility or directly in Cydia.

Old devices like iPhone 3GS (old bootrom), iPhone 3G and iPod touch 2G (non-MC model) can be jailbroken-untethered right now using this latest version of RedSn0w.

You can download RedSn0w 0.9.6 b4 here.

Next iPhone/iPod/iPad firmare iOS 4.2 is due out soon. What can we expect in terms of jailbreaking 4.2?

Limera1n exploit for 4.2 in most cases is a tethered jailbreak. That means if you have to reboot your device, it will show a “connect to itunes” logo until you run the jailbreak software again.

• iPhone 3G – will run 4.2 untethered. Redsn0w will be updated.
• iPhone 3GS – old bootrom will run 4.2 untethered if done via Pwnagetool while updating from 4.1. Otherwise it will be tethered.
• iPhone 4 – tethered
• iPod 2G – untethered.
• iPod Touch 3G, iPod Touch 4G – tethered
• iPad – tethered.

Tethered jailbreak isn’t that bad for iPads and iPods. But if something happens and your iphone reboots while you’re away from your computer, you cant use the device until you get home and run some tool on your computer again.

We suggest not updating until new expoit will be implemented in new utility.

The community is working on a solution to this to either make the jailbreak untethered or at least semi-tethered. Semi-tethered means the device will at least reboot, but unjailbroken while on the road until you return to your computer.

The iPhone Dev-Team recently has released a new version of RedSn0w for Mac and Windows.  RedSn0w uses the Limera1n exploit to support more devices and adds the ability to restore custom firmware ipsws. The crew promises that now RedSn0w will work with the iPhone 3G, 3GS, 4, iPad, iPod 2G, 3G, and 4G (Not iPod 2G-MC yet).

You can download RedSn0w 0.9.6b2 from here.

Famous hacker Geohot is back and today he released the latest iOS 4.1 jailbreak. It is called LimeRa1n and supports iPhone 3GS, iPod Touch 3G, iPad, iPhone 4, iPod Touch 4G with iOS firmwares 4.0-4.1 and beyond. It can also hacktivate your device, so there is no need in phone SIM-cards and other tricks.

This software is still in beta and was updated 3 times in last several hours. So use with caution.

There is Windows version only for now. Geohot plans to release LimeRa1n for Mac and Linux soon. You can Download it here.

Some users report that they have jailbroken their iOS 3.2.2 iPads successfully with limera1n, while others report that they tried, but failed.

Do not forget to backup.

For many users of iPhone 3GS and iPhone 4 with iOS 4.0.2 now there is a hope to perform jailbreak using LimeRa1n and unlock using ultrasn0w. We recommend NOT to do it if you have not saved your SHSH keys. You can try, but if something goes wrong without SHSH keys you’ll have to restore to iOS 4.1, and there is no unlock for iOS 4.1 (possibly forever). Just wait for PwnageTool utility.

DevTeam reported that Limera1n uses a different exploit than SHAtter, so they will not release SHAtter utility, they don’t want let Apple fix both security holes. However they plan to release PwnageTool using the same exploit.

Known bugs:

• some people must reboot to see Cydia
• beta iOS versions aren’t supported
• iPod Touch 2G support coming soon
• for iPhone 3G use redsn0w 0.9.6 b1

Here’s a quick changelog of recent beta releases:

• BETA1 – first release
• BETA2 – fixed kernel patching magic, rerun BETA2+ over BETA1
• BETA3 – fixed new bootrom 3GS
• BETA4 – uninstall fixed, respring fixedish

RedSn0w 0.9.6 b1 for Mac OS X was released a while ago. Today DevTeam created a version for Windows users. RedSn0w 0.9.6 b1 can jailbreak iOS 4.1 and iOS 4.1 running on iPhone 3G or iPod touch 2G.

You can download it here.

Redsn0w is easy to use:

1. Download firmware here.
2. Launch redsn0w 0.9.6 b1
3. Select your stock 4.1 or 4.0 ipsw (you’ve already used this to update your device to 4.1 or 4.0)
4. Select “Install Cydia” and any of the other options shown above, then click “Next”. Use DFU mode to install the jailbreak.

This is still beta, so there might be some problems:

Any Windows users seeing “Waiting for reboot” for too long (more than 20 seconds or so), please try “shaking” the JB process by unplugging then replugging your USB cable (while letting redsn0w continue to run). Also, try using a USB port “closer” to your computer (as opposed to on your monitor or behind another hub).

As usual DevTeam reminds us:

IF YOU USE THE ULTRASN0W UNLOCK, PLEASE WAIT FOR PWNAGETOOL TO SUPPORT 4.1. DO NOT USE REDSN0W

That’s because to use redsn0w at 4.1, you need to already have updated to official 4.1 from Apple. If you do that, you lose the ultrasn0w unlock (possibly forever).

DevTeam recently released new version of redsn0w to jailbreak iOS 4.1. New RedSn0w 0.9.6 b1 supports iOS 4.0 and iOS 4.1 running on iPhone 3G or iPod touch 2G.

There is only Mac OS X x86 version, that you can download here.

Redsn0w is easy to use:

1. Download firmware here.
2. Launch redsn0w 0.9.6 b1
3. Select your stock 4.1 or 4.0 ipsw (you’ve already used this to update your device to 4.1 or  4.0)
4. Select “Install Cydia” and any of the other options shown above, then click “Next”.  Use DFU mode to install the jailbreak.

As usual DevTeam reminds us:

IF YOU USE THE ULTRASN0W UNLOCK, PLEASE WAIT FOR PWNAGETOOL TO SUPPORT 4.1.  DO NOT USE REDSN0W

That’s because to use redsn0w at 4.1, you need to already have updated to official 4.1 from Apple.  If you do that, you lose the ultrasn0w unlock (possibly forever).

You cannot use JailBreakMe method to jailbreak and unlock iOS 4.0.2 on iPhone 3G. However you can still jailbreak and unlock iPhone 3G using redsn0w. Here are the instructions:

• Download the latest RedSn0w 0.9.5-b5 in our utilities page here.
• Download firmware images for iOS 4.0 here.
• Run RedSn0w and point it at the 4.0 IPSW. (Yes – point it at the 4.0 IPSW even though you’re at 4.0.2). This will also hacktivate your iPhone3G at 4.0.1 if you haven’t already been activated by iTunes.
• If you need a carrier unlock – install ultrasn0w in Cydia (add repository http://repo666.ultrasn0w.com). For T-Mobile in the USA remember to turn off 3G mode in Settings→General→Network.

During Jimmy Kimmel’s live show Justin Long picked up his iPhone to share some interesting SMS he had. Meanwhile he also showed Cydia on his iPhone’s main screen. For those of you who do not know anything about this man, Justin Long is the very guy who starred in the most popular and successful commercials called “Get a Mac” by Apple, which appeared between 2006-2009 years.

Now that he no longer works with Apple, he is not afraid to break the rules of his former employer. By the way, today jailbreaking is fully legal in the USA, is not it?

Have you already updated your device to the version iOS4 and want to unlock your 3GS? Firstly there was Redsn0w, now PwnageTool is available, which can easily help you. Here is a simple and easy course for jailbreaking of your device. Warning: this is not an official release and therefore may be some bugs that can destroy your device or delete some important information. So be careful while using it!
