Not a huge surprise, as the Nokia Lumia 510 was spotted out and about recently. But it's nice to see some official confirmation of its existence.This is a new Nokia Lumia, but it isn't a Windows Phone 8 smartphone. As Nokia indicated some time back, it plans to use the Windows Phone 7.5 platform for its budget range of Lumia phones, where the hardware criteria is a little less strict. This is the first instalment of that policy, with more likely to follow in the coming months.'With the Nokia Lumia 510 we continue to meet our commitment to bring Windows Phone to new, lower price points,' said Jo Harlow, executive vice president of Nokia Smart Devices. 'People who use Windows Phone quickly realize how much more intuitive it is than other smartphone platforms, and Nokia Lumia is the best embodiment of the Windows Phone experience. With the Nokia Lumia 510 we're looking forward to welcoming more people into the Windows Phone experience.'If you are considering joining that particular club, you'll want to know what the phone offers. Nokia confirms that the 510 comes with a Snapdragon S1 800MHz processor, a 4-inch WVGA 800x480 TFT display, a 5-megapixel auto-focus camera, 256MB RAM, 4GB of memory and 7GB of free SkyDrive storage. Also note that there's no memory card slot here, should you think that storage is a little paltry for your needs.Of course, you also get Live Tiles, People Hub, access to Microsoft Office and Internet Explorer 9 on the go. Downloading the Camera Extras app also provides exclusive digital lens functionality to go with the camera, while Nokia Maps, Nokia Drive and Nokia Transport should keep you on the move.The Nokia Lumia 510 will be available in red, yellow, cyan, white and black, with a price estimate equivalent to £125. On the downside, there is no UK shelf date as yet, although the general rollout will start in November 2012.
