While JailbreakMe.com may be the easiest method to Jailbreak, it doesn’t work with 4.1 firmware. You can use Limera1n to jailbreak 4.1 devices and it’s almost as easy.
- Download the Limera1n installer from the source link below
- Connect your iOS device to your computer
- Launch the Limera1n program. You may have to run the program as Admin in Windows
- Click “make it ra1n”
- Now you must put the device into DFU mode. To do this, hold down the Home and Power button to 5-7 seconds. Then, release the Power button, and continue to hold the Home button for an additional 10 seconds or so. Don’t worry if iTunes pops up.
- That’s it! You’ll see a new Limera1n icon on your home screen, which will allow you to download Cydia, which you’ll need to grab jailbreak apps.
