Saurik has released Cydia Impactor a tweak that lets you 'unjailbreak' your iPhone, iPad, and iPod touch without requiring a restore.
You may want to do this in order to sell your device to someone else and retain its ability to jailbreak or if you are noticing problems with your setup and want to start over with a reasonably fresh install.
How It Works: All files on your device that have been modified or otherwise destroyed are downloaded directly from Apple. In a series of carefully calculated file migrations, all new files are moved to the user partition, and all system data is moved back to the system partition.
Up until this point, the idea is that no changes to your system have been made that are "unsafe": at any point, if Impactor fails/crashes or your device reboots, you can just run it again later. Finally, all of the staged changes to the filesystem are "committed", all user data is deleted, and iOS is told to run its "reset all content and settings".
The idea is that this "critical window" lasts only the final few seconds of a process that lasts for multiple minutes. (That said, I still highly recommend not at all "messing with" the app while it is running, and maybe if you have a lot of data this will take longer than I expect.)
When the device reboots, it will look as it did when you first turned it on; it will also no longer be "jailbroken": if you want to jailbreak it, you will need to do so using a desktop jailbreaking tool.
You can find more details in the package's description in Cydia.

Would it be possible to do an OTA upgrade after using this tweak? Usually it is not possible to do an OTA upgrade in a JB device.
I am asking because I have a JB iPhone 5 with a broken lightning port and I am not able to update it via cable and as it is JB I am not able to update OTA.
I can't imagine a iPhone without a jailbreak gosh! Apple should continue playing the cat and mouse game, instead of finding options to kill the jailbreak forever
Apple stops jailbreak every update to ensure a more secure iOS build from other potential hackers. Once a jailbreak team finds an exploit, Apple finds a way to fix it before hackers find a way to manipulate it and steal from users.
I've always thought Apple's BEST option is to add an user-selectable option to cap the weaknesses in the OS which allow jailbreaks. That would prevent the JB community from digging around in the OS looking for holes. Even better, if you could voluntarily disallow jailbreaks, it would put a break on law enforcement jailbreaking your phone if you're stopped for speeding and they're searching for something to charge you with.
Why would Apple kill jailbreak? They know how much users would want to do anything to their device. It's not like apple controls the phone itself like it has a mind of its own.
Imagine you have an Iphone 4 or 4S on iOS 7 jailbroken and want to sell it with iOS 7 because iOS 8 is lagging on this devices, i have been waiting for this tool.
Why would anyone unjailbreak their device?
I didn't buy an Iphone6 until the jail break came out ,as matter of fact for every Iphone Ive bought
Cant imagine an Iphone without a Jailbreak
