Nokia's efforts may all have been going into selling the merits of the new Lumia 920 and Lumia 820 Windows Phone 8 phones recently, but it hasn't forgotten about Windows Phone 7 just yet.
In fact, it's on the verge of introducing a new face to the more affordable end of its smartphone portfolio: the WinPho 7.8-fuelled Lumia 510.
A smartphone going by that name has just been before the Chinese telecom certification board looking for a green light, and the filing gives us a fair bit of spec goodness to chew on.
We can already deduce a fair bit from the name itself, as Nokia's naming hierarchy isn't particularly complicated: the higher the number the further up the smartphone ladder we're talking about.
So with the Lumia 510 the first 500-series Lumia, we can already be sure it'll be the most budget-friendly Nokia Windows Phone yet.
The presence of Windows Phone 7.8 Tango rather than the newer WP8 (Apollo) reinforces that, of course, as does the rest of the detail: 4in LCD screen, 5-megapixel camera, 800MHz processor with 256MB of RAM.
We've been given a couple of pics too, and from the looks of things the Lumia 510 will very much be a down-the-middle kind of phone: not unattractive, but also doing nothing at all to get the pulse racing.
So when are we likely to see it? Don't know. In fact, there's no guarantee we will. Nokia's Windows Phone adventure has thus far been conducted very much on a horses-for-courses basis. So the Lumia 510 could have been conceived with specifically the Far East in mind.
All will no doubt become clear before too long – or so we hope, anyway.
