I turned the phone on this morning and it said an update was ready go to verzionwireless /lumia929support. Since I had the Developer Preview I started researching what steps I needed to take. Then I decided to check Setting->extras+info. I first clue was new options under settings: Hey Cortana, motion data and transfer my data. When I touched extras+info I was pleasantly saw Lumia Denim. I scrolled down to see creation date 1/9/2015. Every indication is this is the real Denim. AND I did not have to "remove" Preview for Developers. It seems to have integrated/updated what was already installed. I know it is Demin. It paired with my Fitbit One and Chest Strap Heart Rate Monitor. Finally, thank you Verizon.
