December 2008; Middletown, New York: A trio of thieves intent upon stealing car parts from an auto body shop in upstate New York foiled themselves when the cell phone one of them was carrying "pocket dialed" 911, resulting in police overhearing their conversation as they were robbing the place: "You better come! We're getting the tires -- just shut the car off. They're going to think we're stealing it!" The GPS function on the phone led police straight to the miscreants.
April 2005; Rogersville, Tennessee: Hawkins County authorities were tipped off to two would-be burglars' plans to steal a refrigerator from a mobile home dealership when a cell phone one of the crooks was carrying in his front pocket relayed a 40-minute-long discussion about the upcoming heist to 911 dispatchers. (The phone was of a type that automatically calls 911 when the '9' key is held down.) Sheriff's deputies hid in the woods near the dealership and nabbed the hapless thieves as they exited one of the mobile homes with a refrigerator and set it on the ground outside.
March 1997; San Diego, California: Trying to call Mexico, a drug dealer dialed 911 instead of 011.

Four bad guys were arrested and 42 lbs. of marijuana and 2 oz. of methamphetamine were seized.
February 1994; Laguna Nigel, California: A man programming his phone to speed-dial 911 (Huh? The number is that hard to remember?) was arrested when sheriff's deputies responded to his call. He and his two buddies appeared to be under the influence of crystal methamphetamine and drug paraphernalia was found in the apartment, so the three of them were placed under arrest.
February 1990; San Diego, California: A phone programmed to automatically dial 911 when bumped or dropped gave this set of crooks away. Police discovered 250-300 marijuana plants growing in the house they'd been sent to investigate.
