From the CES in Las Vegas: Updating their existing BlackBerry Curve 9360 or 9380 models to the just-announced OS 7.1 will activate the existing FM chip in those phones. BlackBerry parent Research in Motion says the new app "allows users to tune in and enjoy local FM radio stations" without using a data plan. In other words, the phone becomes an FM radio. Radio executives such as Jeff Smulyan at Emmis have long contended that millions of smartphones already in consumers' hands possess FM circuitry that simply needs to be activated. Other advances for BlackBerry phones include: "Tag", making sharing of information with fellow BlackBerry users easier. And the ability to turn the phone into a mobile hotspot that feeds up to five Wi-Fi devices.
