I used limera1n with my windows PC. I really don’t know how it works with Mac but I will research it if needed. Download limera1n like you download any software. My suggestion is to save it. You can save it on your desktop or wherever you usually save your downloads.
Double click the limera1n.exe file to launch the application. Your Iphone needs to be connected via USB when you perform this action.
Click the make it ra1n button when it appears.
Your phone is now in recovery mode.
Press both the home and power buttons (on your Iphone)
When the Sotware asks you, release the power button.
The screen will show that your phone is in DFU mode
As the software performs it task, you will see an image of a lime raindrop on your Iphone.
When the Software is done, it will let you know.
After you power back your Iphone, you will see a new icon on your Springboard called limera1n. Press it to continue.
Once limera opens, select Cydia then press Install button at the top right of the screen.
Once Cydia installation is complete, reboot your iphone. When your Iphone restarts press the Cydia icon and let it update.
Your Iphone is now Jailbroken and you can download Apps and themes via Cydia. You can research Cydia further over the internet, it works fine for me 🙂
How about the unlocking? This will come in my next post as unlocking is a hassle on its own.
