These are instructions on how to jailbreak your iPhone 3GS and iPhone 4 using Limera1n for Mac. Limera1n supports iOS 4.0, 4.0.1, 4.0.2, and 4.1. You can find the Windows version of this tutorial here.

Remember: Do not update to iOS 4.1 if you need the unlock. Ultrasn0w does not support that baseband yet. The only exception is the iPhone 4. You can update to iOS 4.1 without upgrading your baseband by following this tutorial.

Step One
Open your web browser of choice and navigate to Click the Mac logo at the bottom of the screen.

Step Two
When prompted save the download to your desktop

Step Three
Double click the file from the desktop to extract the application, then double click it to launch.

Step Four
Connect your iPhone to the computer and click the large make it ra1n button

Step Five
You iPhone will now be placed in recovery mode.

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 Six
After you power back on your iPhone you will see a new icon on the SpringBoard entitled limera1n. Press it to continue.

Step Seven
Once Limera1n opens select Cydia then press the Install button at the top right of the screen.

Step Eight
Once the Cydia installation has completed you must reboot your iPhone.

Step Nine
When your iPhone has restarted you can run Cydia. Let it do all the necessary updates then follow our Unlock tutorial if possible for your device.

NOTE*: To remove the limera1n icon from your desktop you can relaunch the app and tap the Uninstall Limera1n button or install CyDelete from Cydia then use it to delete the application.

***A big thanks goes everyone who made this jailbreak possible.

I tried to jailbreak my iPhone 4 with 4.0.2 and 1.59.0 but each time I get the message Retry Hold Home and Power. I think it has to do with the fact that iTunes starts each time saying that it detected an iPhone in Recovery mode. Any idea what I can do? Thanks

Tried limera1n against 3GS 4.0.2 new bootrom 5.13.04 baseband. Appeared to work fine but after boot the limera1n icon did not show. Tried many times to no avail. I finally did a factory reset (erased all data/settings) from the phone and after boot the limera1n icon showed up. Just wanted to point this out just in case anyone is running into same problem

I tried on 3gs 4.0.2 5.13 couple of times on PC but the Limera1n would not install on the phone, then factory reset the phone and ran Limera1n and was successfull, now downloading Cydia. Excellent utility, keep it up.

I\'m in the same situation -- I need to jb and unlock a 4.0.2 on a 3GS/old bootrom and Limera1n acts like it\'s installing but no icon ever shows up. But I\'m afraid to do a \"factory reset\" -- what iOS does it reset to? Do I risk losing my 5.13.04 baseband?
