Apple has recently rolled out iOS 6.1.3, which is said to be an incremental update to its mobile operating system running iPhone, iPad and iPod Touch. This software update fixes the lock screen bug which enabled anyone to easily bypass the passcode and thereby get access to the personal information on the iOS device. The update also contains Maps improvement in Japan.

The iPhone 3GS, iPhone 4 and iPod Touch 4G users who have already upgraded their device with the latest iOS 6.1.3, may follow our step-by-step instruction guide below to jailbreak the same using Redsn0w version 0.9.15b3. IBTimes UK reminds its readers that it will not be held responsible for any damage to the device.

Pre-requisites

1) Users are reminded that the Redsn0w 0.9.15b3 supports only tethered jailbreak which means they need connect the device to the computer on every reboot except iPhone 3GS with older bootrom.  

2) This tethered jailbreak is compatible with pre-A5 devices such as iPhone 3GS, iPhone 4 and iPod Touch 4G. 

2) Currently it is not possible to jailbreak devices such as iPhone 5, iPhone 4S, iPad 2, iPad 3, iPad mini and iPod Touch 5G

3) Back-up all the data of the iOS device before proceeding.

4) Ensure that the battery of the device carries above 80 per cent of charge.

5) The tutorial below uses an iOS 6.0 jailbreak with the iOS 6.1.3 file system, therefore it is likely to create some unknown issues.

Compatible device:

iPhone 3GS

iPhone 4

iPod Touch 4G

Steps to jailbreak iOS 6.1.3 tethered on iPhone 4/iPhone 3GS/iPod Touch 4G using Redsn0w 0.9. 15b3

a) Hold the Power button on the iOS device for three seconds

b) Simultaneously, hold the Home button and keep pressing these two buttons for 10 seconds

c) Now release the Power button while keep holding the Home button until Redsn0w detects the device

8) The iOS device should reboot now. The device will reboot again and Redsn0w will now begin uploading the new RAM disk and kernel
