Nokia has finally rolled out Microsoft's incremental Windows Phone 7.8 update to the Lumia 900 handset.
For example, Windows Phone 7.8 offers a taste of Microsoft's new Live Tile-based interface, giving users of eligible devices a far greater scope for home screen customisation than they enjoy on Windows Phone 7.5.
Other improvements include resizeable widgets, a new lock screen featuring Bing wallpapers, additional colour themes, and a host of updated logos.
The Windows Phone 7.8 boost will be the final upgrade of the Windows Phone 7 generation, Microsoft has previously confirmed.
In related news, Nokia is gearing up to launch its next top-of-the-range Windows Phone 8 smartphone.
A great deal appears to rest on the forthcoming handset, after Nokia CEO Stephen Elop faced a grilling from his company's shareholders at its recent annual general meeting in Helsinki.
Elop was accused by one investor of leading Nokia down a "road to hell" by insisting on maintaining an exclusive mobile focus on the Windows Phone platform.
