Microsoft's Lumia Denim Release is Coming for Windows Phone

Microsoft confirmed Thursday that it had begun rolling out its Lumia “Denim” update for WIndows Phone, officially bringing Windows Phone 8.1 Update 1 and improved camera functionality for supported devices.
Microsoft is pushing Denim somewhat piecemeal across different geographies and phones, however, so some of the features may arrive on different phones at different times. And there's no official timetable to bring it to the United States—although it should arrive on American shores
