Jailbreak iPhone, iPod Touch, iPad

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.

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

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.

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.

Having problems activating your iPhone? Don’t have original SIM-card? Cannot get passed emergency unlock screen? We have a solution:

If you have iPhone 3G, just use redsn0w to jailbreak and hactivate. If you have iPhone 3GS or iPhone 4 follow these instructions:

If you are already Jailbroken:

So you have an iPhone with iOS 4.0, but don’t have the original SIM and stuck on the Emergency Call Screen:

1. Download ifunbox software (download link)
2. Run ifunbox software and sync with phone
3. Go to /private/var/root/Library/, delete original lockdown folder and put this lockdown folder after you extract it from the zip file
4. Restart phone

If you are not jailbroken

Sherif Hashim discovered that you can activate your iPhone 4, iPhone 3GS or even iPhone 3G without the original carrier SIM card. You need a “phonebook sim card” or 02 simcard. You can buy these type of sim at radioshack, bestbuy or other mobile electronics store (for example here).

Once you get passed the Emergency Call screen, connect to Wifi, jailbreak using JailbreakMe.com and unlock using ultrasn0w. Once that is complete you should be passed activation and unlocked (able to use any sim). If you get a different simcard error, do the following final step:

1. Download ifunbox software (download link)
2. Run ifunbox software and sync with phone
3. Go to /private/var/root/Library/, delete original lockdown folder and put this lockdown folder after you extract it from the zip file
4. Restart phone

If you have itunes invalid response problem:

1. Connect to wifi and ssh to your phone (via winscp, putty, terminal, etc).
2. Navigate to your lockdown folder (/private/var/root/Library/).
3. Delete pair_records folder
4. Reconnect the cable and see that your invalid response problem is gone.

If you bought your iPhone 4 on ebay you will need the official sim (at&t) or a universal sim, like ones you can grab at bestbuy for $10 this will get you passed Emergency Screen.

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.

MuscleNerd, hacker from DevTeam, commented via twitter on recent rumors that universal jailbreak (all iPhones and all firmwares, including iPhone 4 and iOS 4.0.1) will be released today. The basic answer is no, there will be no jailbreak today.

Not to make it a daily thing, but since somehow people thought it would be today: the new JB+unlock won’t be out today

(there are issues with important apps like Facetime that need to be figured out…no sense releasing a half-broken JB)

Jay Freeman, better known as Saurik, the creator of Cydia, was interviewed by the home radio Make It Work. He speaks about the history and the future of the iPhone jailbreak.

Saurik describes the origins of Jailbreak and Unlock for the very first model of the iPhone. Jay explains that initially there were two important things to do with the iPhone 2G -- to use other carrier than AT&T and to install any application.

He continues discussing the main applications from Cydia. Cycorder was the first to allow video recording, and Winterboard was the only one that allowed users to change the graphical interface of the iPhone. He also speaks about Comex, the hacker who is currently working with the Dev Team for releasing and Unlock for the iPhone 4. According to Saurik the tool is still not ready to be released to the public due to severe bugs in the code. Here the second part:

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)
