At long last, a jailbreak method has been released for iOS 6 and higher, which makes this the first jailbreak for the iPhone 5.
If you've been waiting to jailbreak your iPhone 5, or any device running iOS 6 and higher, the wait is over. The Untethered jailbreak for new idevices is released. A new tool Evasi0n is released to jailbreak your phone.
Compatible with all iPhone, iPod touch, iPad and iPad mini models running iOS 6.0 through 6.1.2
Note : Before starting process, make sure :-
1> Make sure you are on latest iOS version i.e. iOS 6.1.2 and make sure that when you upgraded to iOS 6.1.2 via itunes update, not via an OTA update. While it’s possible that it will work, OTA updates have caused known problems in the past with regard to jailbreaks, it’s best to just play it safe.
2> Before you start, make sure you have a current backup of your iOS device. You can back up through iTunes or use iCloud. The choice is yours. This is a crucial step to ensure you don't lose important data should something go wrong and you have to restore.
3> If you use a passcode on your iOS device, the evasi0n team suggests disabling it before you being the jailbreak process; apparently it can cause issues. You can disable your passcode in Settings > General > Passcode Lock.
Now, lets get started
Step 1: Head over to official website www.evasi0n.com and download appropriate setup, its available for window/mac/Linux. Download the latest version i.e V 1.5
Step 2: Save the evasi0n app to your desktop, and run it.
Step 3: Connect your iOS device to evasi0n, and ensure that evasi0n detects your device. Evasi0n should work with any iOS 6 firmware from iOS 6.0 to iOS 6.1.2. In this case, you will be using iOS 6.1.2.
Step 4: Click the jailbreak button, and the jailbreak process will begin. Be patient, as this takes a while. You will notice your device reboot several times throughout the entire process. The main thing is just to be patient.
Step 5: Eventually, evasi0n will ask you to unlock your device, and tap the Jailbreak icon on your Home screen once. Follow these instructions, ensuring that you tap the icon only one time, and then leave the device alone and let it continue.
Step 6: The evasi0n app will complete its course, and you will be able to click the Exit button. The iOS device, however, still needs to finish up a few additional steps, so again, be patient and don’t touch your device.
Step 7: Eventually, the jailbreak will finish, and you can unlock your iOS device, and open the Cydia app on your Home screen. Cydia will need to initialize, which takes about 1 to 2 minutes. After the initialization is complete, the device will respring again.
Step 8: Reopen Cydia, select Hacker, and begin enjoying your newly jailbroken iOS device running iOS 6.1.2.
congrats!! Now your device is Jail-broken \m/
