If you're a Lumia phone owner, you no longer have to get lucky (or install a preview release) just to get all of the latest Windows Phone features. Microsoft is about to startthe wider rollout of Lumia Denim, a Windows Phone 8.1 Update 1 upgrade that packs a lot of improvements to both imaging and Cortana voice commands. It's not saying exactly who's a candidate in this next wave, but many countries and devices will start seeing Denim later this month -- depending on how quickly the carriers finish testing, of course. Verizon already brought Denim to the US through the 822 and 928 back in December, but the broader deployment suggests that other American Lumias are due relatively soon.
