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

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.

Engadget published a howto video of LimeRa1n – iOS 4.0-4.1 jailbreak utility for iPhone, iPod Touch and iPad:

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
