Jailbreak iPhone, iPod Touch, iPad

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).

Steve Jobs, Apple’s CEO, confirmed that the new software update iOS 4.x will appear in the near future to correct performance problems on the iPhone 3G, which works on iOS 4.x. He confirmed it while answering to the email he got from a user who was disappointed with the iPhone 3G performance running on iOS 4, describing it as “dog slow”.

Although he did not mention a specific version or date of its release we can guess that he was specking about iOS 4.1, which is going to be released next month, when iTV (Apple TV) and the next generation iPod touch will spotlight.

MuscleNerd tweeted today that the recent redsn0w utility is able to jailbreak the iOS 4.1 beta2 on iPhone 3G and iPod Touch 2G. This is useful for developers only, however good news for everyone.

Here’s some info from the DevTeam wiki page:

If you’ve updated to 4.1beta2 on iPhone3G or iPod2G(non-MC), you can use this redsn0w from June to jailbreak. Just point it at the 4.0 IPSW (the public one, not the developer GM one).

(Yes – point it at the 4.0 IPSW even though you’re at 4.1beta2).

Don’t do this if you need the ultrasn0w carrier unlock!!

Note 1: This won’t hacktivate your iPhone3G – but for those with legit access to the 4.1beta2 this shouldn’t matter. Please don’t pirate Apple software

Note 2: If you’re at 4.1beta2 you’ll probably experience network problems after jailbreaking. Until a new version of redsn0w is released, you may need to rely on afc2 access (such as FunBox-like file browser programs) to manipulate your filesystem.

Note 3: This is recommended only for power users who can deal with the problems that will pop up as the JB apps fall further behind the beta firmwares.

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 updated iOS 4 jailbreak utility redsn0w to version 0.9.5b5-5. That should fix any APN or MMS issues that users were seeing. It’s safe to re-run it on an already jailbroken iPhone without restoring. Just deselect “Install Cydia” if you do that.

Supported devices are still only iPhone3G and iPod Touch 2G (not MC)

You can download the latest version here.

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.

Finally the jailbreak for iPad, iPhone and iPod Touch from the Dev Team is available for download. It’s free and untethered and it’s called “Spirit”. The jailbreak supports every iDevice with firmware version 3.1.2, 3.1.3 or 3.2.

If you have iPhone 3GS or an iPad you should backup your SHSH blobs before using the jailbreak. ECID SHSH or SHSH blob is a unique signature given to every Apple mobile device. When you decide to restore the firmware on your iPhone, iPod Touch or iPad, Apple servers checks this signature.

As you know, if a new firmware is released it becomes impossible to restore the older firmware from iTunes. But Cydia creator tuned up a new server and now it mimics Apple’s verification server and saves your older SHSH blobs so that you can restore back your device to the older firmware. Without having your SHSH blobs saved you may accidentally update new firmware and then you not only lose your jailbreak but also won’t be able to restore the older firmware to re-jailbreak your device.

This is also important because there is a big possibility that Apple will soon find out what exploit is used by the jailbreak and then it will be patched in the form of new firmware.

You can save your SHSH blob in three ways. Here is a guide to make it using AutoSHSH.

1. Download AutoSHSH. (Latest version is here).



2. Start AutoSHSH and plug in you iPhone/iPod Touch/iPad in recovery mode (only one device at a time). Recovery mode launches when you turn off your device and hold down the “Home” button when connecting the USB cable. Then you must see “Connect to iTunes” message and logo on your device.



3. In AutoSHSH click on “Grab my SHSH Blobs Automatically”. When the app will grab the signature you must choose whether you want to save it locally or not. Do not forget where you saved the signature. In the end of the procedure AutoSHSH will also upload it to saurik’s server.

If you have some problems with using AutoSHSH to save your blobs, write it in comments or try saurik’s method or Firmware Umbrella instead.

Now, when you saved you SHSH blobs, you can make the jailbreak. It is recommended for you to sync your device with iTunes beforehand. Then use the following guide:

1. Download “Spirit” (link for Windows, link for Mac OS X).
2. Plug in your device (it will be instantly recognized).
3. Hit the “Jailbreak” button.

That’s all!

Additionally here is a video tutorial for jailbreaking:

Please note that Spirit is not a carrier unlock so it won’t allow you to use unauthorized wireless carriers. The jailbreak is also “sort of beta”, so it may be buggy. DevTeam notifies that some apps in Cydia that are NOT designed for iPad may crash your system and require you to restore so be careful.

MuscleNerd just released redsn0w 0.9.5 beta – the first public jailbreak of iPhone OS 4. This utility is only for developers of jailbroken apps, so they can update apps for firmware 4.0. The jailbreak only supports the iPhone 3G and runs on MAC OS X. There is no carrier unlock right now.

You can download RedSn0w 0.9.5 and get more info here.

A few hours ago iH8sn0w posted a tweet that he is able to run jailbreak on the new firmware 4.0 beta 1. DarkMalloc, another developer who worked on the project, has just released new video that shows firmware 4.0 jailbreak on iPhone 3G:

The interesting thing, besides the presence of Cydia and MobileTerminal, is the possibility to have multiple applications open at once. That means that multitasking on iPhone 3G can be enabled. Officially Apple doesn’t want to activate this functionality on iPhone 3G, just iPhone 3GS and later devices.
