Do you have a "My cell phone saved me!" story to tell?

One time I was on a narrow 2-lane road approaching an intersection. There was a car parked at the curb on the other side of the of the street, effectively making the intersection one lane. A thug in a beater pulled in, in my lane, and stopped. Another thug comes out of the house, gets in the car, and commences to waving for me to back up and let them through. Pre-cell, I would have been intimidated and moved. As it was, I just pulled my cell out and opened it. “Yeah. Come assault my car while I read 911 your license number.” The driver thought better of it, and backed out.

Care to share a time when your cell got you out of a jam, where you otherwise probably would have been injured or intimidated?
