Evasi0n is finally here to enable all iDevice owners to break the shackles and install mods, themes and tweaks on their iOS 6 iPhones, iPads, and iPod touch players. This guide here will show you how to do that.
Before we begin, we need to stress that Apple doesn’t condone jailbreaks. In the offset chance that something goes wrong with your device in the future, the company may refuse service on the count of your hacking it.
With that out of the way, the team responsible for Evasi0n (the evad3rs) also has some important notes for would-be jailbreakers.
"Backup your device using iTunes (or iCloud) before using evasi0n. If something breaks, you'll always be able to recover your data."

Here are some important notes from Evasi0n’s release notes:

• Those who use backup passwords in iTunes must disable them for now. After doing so, iTunes makes a brand new backup. Please wait for that backup to complete before proceeding! Feel free to re-enable your backup password after jailbreaking.
• Please disable the lock passcode of your iOS device before using evasi0n. It can cause issues.
• Avoid all iOS and iTunes related tasks until evasi0n is complete. Why not just enjoy a brief break from the computer to stretch your legs?
• If the process gets stuck somewhere, it's safe to restart the program, reboot the device (if necessary by holding down Power and Home until it shuts down), and rerun the process.”

With that out of the way, here are the actual steps required to jailbreak an iPhone, iPod touch or iPad running iOS 6.0 through iOS 6.1 using Evasi0n.

Method To Jailbreak iOS 6.1:
> Download the Evasion Tool from the link given below.
> Now, drag it to your desktop and open it.
> Now, plug the device which you want to jailbreak in your pc.
> Evasion will recognize your device details. Then, click JAILBREAK button.
> Now let the Evasion do everything for your device. It will ask you to unlock your device and tap a new “Jailbreak” icon that has been miraculously added to your Home screen.
> After jailbreaking, your device will reboot and you will see the new Cydia icon on your home screen.
> That's it. Enjoy.
