In a small, but significant bit of news, Verizon has started pushing the Lumia Black update
to all Lumia 928 owners in the US. Further confirmation comes from Nokia's Global Support page, where the update is listed as "available". After installation, your phone's software will be updated to version 3051.40000.1352.0058. If you haven't received the update yet, go to the Settings menu and tap Phone Update for a manual check.
Lumia Black brings a selection of Nokia apps, such as Glance screen 2.0, Refocus, Beamer, Storyteller and Camera. Further new features include Bluetooth LE, image quality improvements, safe driving mode, customized ringtones, and additional under-the-hood tweaks.
