Sometimes an iPhone can literally be a life saver.

FOX's Steve Rappoport explains:

Christopher Beaucher went to check on his mother's vacant cottage in New Hampshire two weeks ago, but something didn't look right. Once inside, he flipped the light switch and the house suddenly exploded.

Beaucher suffered burns to his face and hands and thought he was going into shock, unable to dial 911. He turned to his iPhone's trusty sidekick Siri... Asking the virtual assistant to call for help. Beaucher is still undergoing treatment for his injuries and hopes to return to work soon.

Officials investigating the cause of the blast.

You're a real hero, Siri... And so humble too.
