It would seem that it may be nothing easier than restoring iPhone from iTunes. This post I will dedicate to this topic. And so, in this article I’ll describe the processes of restoration and renovation of any iOS devices (iPhone, iPad or iPod Touch) to iOS 6.1.2 and without updating to iOS 6.1.3 in the future to keep jailbreak. The main aim of restoring iOS device is reset it to factory settings with the iOS upgrade. The difference between updating and restoration is when you restore the device to factory settings” (clean system), all user data will be deleted. So you need to backup device before the process.
