How could an iPhone tell it's being stolen?

Lots More Information

Author's Note

The first thing I thought of when I read through this patent application was, is Apple building the car-alarm equivalent for iPhones? And then I thought of how a good hail storm can set off a car alarm. What would the sensitivity of the iPhone alarm be, and how many people would be running to meetings with iPhone alarms sounding from their pockets as they go? While the technology doesn't yet exist (this patent was filed after the iPhone 5 was released), rest easily -- if this accelerometer-based theft device comes to pass, it sounds like there will be plenty of ways to adjust its sensitivity, or, just turn it off.
