In a recent decision in the case of The People vs. Gregory Diaz, the California Supreme Court upheld a criminal conviction based on a warrantless search of the suspect's cellular phone incident to his arrest. The Ventura County police had been surveilling a drug deal though a wire worn by a police informant. After the drug deal went through, police officers pulled over the drug dealer and arrested him. At the time of the custodial arrest, police found some drugs and a cell phone on the dealer's person. When the officers interviewed the dealer at the precinct he first denied the drug deal. But when the officers showed him the text message on his cell phone indicating the drug price, he admitted to the deal. Later, the dealer moved to suppress the evidence as the fruit of illegal search and seizure under Fourth Amendment to the United States Constitution. However, the California High Court upheld the search and the evidence found.

Most people know that their cell phone has a global positioning system (GPS) that would allow the phone company to track where the cell phone is located at any point in time. Many do not realize, however, that the photographs taken by the cell phone will embed on them the GPS coordinates of the location. Therefore, this so-called "geo-tag" information may inadvertently give away a person's private information such as their residence address. Some commenators have raised concerns about these hidden codes embedded on photographs, and their effect on privacy laws.
