so those pretty Lumina 900s, released less than a month ago, will still be getting new apps, right? Android and apple screw existing customers with release cycles, but this may be a new low
Not a screwjob at all. While Windows Phone 7 and Windows Phone 8 might LOOK the same, they are very different as far as the software is concerned. Windows Phone 8, from my understanding, shares it's codebase with Windows 8. Windows Phone 7 does not.
Also, I believe, there are different hardware requirements so trying to retrofit Windows Phone 8 software on Windows Phone 7 devices, even if it could be done, would not produce a very good user experience.
