The OTA update function was introduced in iOS 5, this function helps users to update to the latest version of iOS without connecting with iTunes. But there are certain disadvantages of this function. For example: Jailbreak doesn’t work with OTA update and after updating OTA, users will not be able to Jailbreak their devices.

Well, if you have already Jailbroken your iDevice, you can search in Cydia forevasi0n 6.0-6.1 Untether and install the update from there. This is the suitable method for all those users who have already Jailbroken their devices and don’t want to use the Evasi0n Jailbreak tool.
