Thieves, beware! A stolen iPhone can explode in your hands and seriously injure you. Yes, you heard us right... the device can blast like a mini bomb. And, this is not happening due to a battery defect or short-circuit. Apple Siri triggers the 'mini bomb' on detecting an unauthorized access on the device.

Siri - the virtual assistant - can set remainder, text or call someone and even help you in making decisions. Siri is the most lovable feature about iPhone 4S. But in Apple's upcoming smartphone dubbed iPhone 5, Siri could possess the power to blow up your phone like a mini bomb if it detects an unauthorized person operating the phone.

A new iPhone 5 concept design video reveals the future of iPhone security feature. The YouTube video comes via courtesy of Aatma Studio, the designer firm renowned for making concept designs of Apple products.

"Everyone has friends whose smartphones have been stolen, so we came up with this extreme measure that a user could enable. If the owner can't have it, no one else should," said Aatma Studio CEO Pramod Modi Shantharam. "The computer generated Siri feature was designed to be a funny concept, while simultaneously pushing the envelope on iPhone security."

Whenever a wrong password is entered three time in a row, which is common in case of thefts, Apple Siri appears with a warning - "Incorrect password. I'm now going to disable the iPhone. Goodbye!" And BOOM, the iPhone screen shatters and the smartphone is permanently disabled, after backing up data on iCloud.

This cool conceptual video shows an innovative feature. But Apple is never going to equip iPhone 5 with this type of technology because it's too dangerous. However, we could see such type of self-destructing technology in future devices though there are few years to go.

We have seen an identical technology in many Sci-Fi and thriller spy movies like Spy Kids or James Bond, where gadgets deliver a message and self-destruct so that the receiver can never postmortem the device to get a clue about the sender. What do you think? Is this a cool feature or not?
