It seems all those video demoes of the Nokia Lumia 920 is continuing to deliver the Windows Phone 8 info which Microsoft is holding onto so jealously.
The latest revelation is the presence of a dark theme in the native email client, something which is not available right now even when you are using a dark theme. The new feature was revealed in a demo video of the Lumia 920 at around the 4:14 mark, which also reveals that composition will still take place on a white background screen.
WPCentral were able to confirm that this was an option in the email client, and was independent of the theme currently chosen.
One wonders what other little features Microsoft is still to reveal in the run up to the release of Windows Phone 8. See the video demo after the break.
