In the shooting that followed the insurgent was killed and Garrad was hit in the chest, although thanks to the iPod, he did not know about it until later.
Apparently the iPod took enough energy out of the bullet that Garrad did not know he had been hit until he took the device out later. The soldier's flack jacket actually saved his life.
It has been reported that an engineer at Apple has brought the story to the company's attention and Apple is looking to replace the soldier's damaged iPod.
