Moments ago, we posted that Limera1n was released to jailbreak all iOS 4.1 devices forever. We promised with how-to guides and here we go, you can now use the step by step guide below to jailbreak iPhone 4 and iPhone 3GS using Limera1n on Windows only.
STEP 1: Download Limera1n for Windows from here.
STEP 2: Connect your iPhone to your PC via USB then launch Limera1n and hit “make it ra1n”
- 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
STEP 5: The jailbreak should be done now. Tap on the limera1n icon on your device and install Cydia.
You have to keep some points in your mind, first, Limera1n will not unlock your device (i.e. you will lose unlock if you upgraded to iOS 4.1 and used limera1n).
Second, Limera1n is not working with old bootrom devices and it doesn't support iOS 4.2 beta, Geohot is fixing the issues right now. Stay tuned.
Limera1n would mess up GreenPois0n jailbreak release as the teams don't want to give Apple two exploits. They would better save one of them to 5th-generation devices.
