Will the Lumia 810 not be getting W10? I have 8.1, but on the site it said phones that already have 8.1 will be able to receive the update. Any ideas??
I'm assuming this is the Developer Preview of Windows 8.1? The 810 is a T-Mobile handset and I recall them pulling the plug on support and updates for it before rolling out Windows 8.1. My bet is you'll have to settle for a stable Dev Preview version.
