Jailbreak iPhone, iPod Touch, iPad

There is no official jailbreak utility for iOS 4.0.1. However you can still jailbreak and unlock iPhone 3G. Just do the following:

• 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 4.0.1). This will also hacktivate your iPhone3G at 4.0.1 if you haven’t already been activated by iTunes.
• Install ultrasn0w in Cydia (add repository http://repo666.ultrasn0w.com) if you need a carrier unlock (and in the USA, remember to turn off 3G mode in Settings→General→Network).

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)

DevTeam hacker Planetbeing has just announced that the iPhone 4 has been successfully unlocked.

Looks like I now have an unlocked iPhone 4.

My soft-unlocked iPhone 4 (in Canada). I’ll have video in a couple of hours once I can top-up the SIM. http://twitpic.com/24ycdv

DevTeam congratulated planetbeing in team’s official twitter:

Congrats to @planetbeing for first ever soft-unlocked iPhone4 http://is.gd/dqwvv (now to streamline it!)

Musclenerd also mentioned one interesting fact:

We think we have 3 different ways to unlock once inside BB (the 3rd way was first to fully work for @planetbeing !)

Congratulations for accomplishing this in such a short time. The unlock will be publicly available shortly after comex releases his jailbreak utility for iOS 4.

Geohot closed the iPhone blog that he used to announce and release jailbreaks and unlocks over the past few years. The site now says “This blog is open to invited readers only”. Yesterday he posted his last public blog entry.

Geohot has also now shut down his Twitter account which has 113,761 followers. Visiting the account now says “This person has protected their tweets”.

His last messages are:

was just having fun but some people had to take this all way too seriously. it’s just a phone, and it isn’t much fun anymore.

my bio isn’t “iPhone hacker” it was just something i did occasionally when i was bored. seriously, i think many of you care way more than me

it was a cool ride, and i’ve learned a lot about a lot. perhaps one of these days i’ll do a more formal goodbye.

Last Geohot’s post on his blog reveals that he will not release any new tool for jailbreak or unlock in the near future. Moreover, he said that he misses those old days, when jailbreaking was a hard work to do:

“…Sorry, this post was probably a bad idea. Next time I won’t say anything. I miss when this blog was actually about technical things (I’ve been reacting too much to the feedback, which led it to the place it’s in now). I didn’t fully realize most of the current scene don’t care unless they are getting something. Now I do. It’s late tonight, I’ll think about what to do about this in the morning.

The real reason behind no release isn’t technical. It’s just that it will never stop, after blackra1n, people demand unlock, after blacksn0w, people demand untethered. I miss the days when jailbreaking and unlocking were difficult, it attracted a much higher caliber crowd.

Also, to the haters, the picture is quite obviously fake.”

Many people have immediately started to buzz that it may be an indication of Geohot’s retirement. Other decided that it is just some kind of a trick and the picture above is not a fake indeed. Hope they’re right.

MuscleNerd, famous hacker from DevTeam, has announced via Twitter that an upcoming comex release will jailbreak all 4.0 devices. This will include latest iPhone 3GS, iPhone 4, new iPod Touch and iPad.

jailbreak for all devices at 4.0 is already handled by upcoming @comex release so, good time for iphone4 unlock stuff

Comex is also well-known, he authored the 3.1.2 and 3.1.3 jailbreak called Spirit. He’s also recently demonstrated Frash, an upcoming release of Flash for the iPhone and iPad.

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.

Apple recentrly released new version of iPhone OS 4. it is called iOS 4.0 GM. Here is an update from DevTeam about iOS 4 jailbreak:

For those who can legitimately activate to the iPhone3G 4.0GM seed, the “point to previous IPSW” redsn0w trick works and will jailbreak your 4.0GM. The “trick” is to point redsn0w at the 4.0beta4 IPSW instead of 4.0GM (do this after you’ve updated to 4.0GM and activated through the new iTunes 9.2 on your Mac). Since the carrier unlocks aren’t yet supported at 4.0, don’t do this if you use yellowsn0w/ultrasn0w/blacksn0w. Many JB apps are still pretty buggy in 4.0, so again this is mostly useful only for developers of those JB apps.

Note: If you’re experiencing MobileSafari crashes, double check that you’re running the version at the bottom of this page.

For those without legit iPhone3G 4.0GM seed access, please wait until the full public 4.0 release for updates to the jailbreak tools.

You can download redsn0w 0.9.5.b4 here.

Last week Apple has released its iPhone Os 4.0 beta 4 and redsn0w is finally updated to support this as well as beta 1. New version of jailbreak is 0.9.5.b4 and it can be applied on iPhone 3G only(!).

Redsn0w 0.9.5.b4 is targeted at developers who make jailbroken apps, and will not work if you are already using blacksn0w, ultrasn0w or yellowsn0w.

iPhone Dev-Team warns:

“You should stay clear of this beta software if you rely on a carrier unlock.”

To use the jailbreak, follow the guide below:

1. Download redsn0w 0.9.5.b4 here. (Only Mac OS X version since app are developed on this OS).
2. Make sure you have already activated your iPhone 3G with iTunes and your own developer ID.
3. Launch the jailbreak.
4. Select your stock iPhone1,2_4.0_8A274b_Restore.ipsw (beta4) or iPhone1,2_4.0_8A230m_Restore.ipsw (beta1) file that you used to update your firmware.
5. Choose “Install Cydia” and then click “Next”. Use DFU mode to install the redsn0w.
6. When your iPhone 3G comes back up, you will notice Cydia has a blank white icon. It also has no sources so you should go to the Sources panel and add this repo: http://apt.saurik.com/cydia-3.7 (make sure you are connected to the Internet before). When Cydia restarts, you should see its real logo now, and the standard sources should be ready to use.
