Although Nokia has released details of its upcoming Windows Phone 8 smartphones, it is still releasing phones based on the older version of Windows Phone. In this case, the just launched Lumia 510 runs Windows Phone 7.5 Mango. The new Lumia 510 is aimed at the low-end of the smartphone market and really isn’t going to be a threat to anything that Samsung, HTC or Sony are shipping.

The entry-level smartphone does have one thing going for it though, it features a 4-inch display which was unexpected as the Lumia 610 and Lumia 710 both have 3.7-inch displays. All three phones have a screen resolution of 800 by 480 pixels. However, besides the display the phone is definitely low-end. There is no front facing camera and the rear camera, although 5 megapixels, has no flash and can only record video in 640 x 480.

It is powered by an aging 800MHz  Qualcomm Snapdragon processor, has 256MB RAM and provides only 4GB of non-expandable storage – no memory card slot here. But don’t worry about the lack of storage, processor power or video capabilities as the Lumia 510 comes in five vivid colors, which according to Nokia, makes “for a fun and personal way to enjoy Windows Phone.”

We all know that Nokia are losing money and market share, and I do feel a lot of sympathy for them, before the smartphone revolution, all the phones in our house were Nokia. When the company jumped off its burning deck at the beginning of 2011 it teamed up with Microsoft to use the Windows Phone OS and Nokia are now stuck with it. The release announcement almost sounds desperate when it says “people who use Windows Phone quickly realize how much more intuitive it is than other smartphone platforms.” Sadly if that was true these “people” would be buying them by the truck load. And almost to make matters worse it points out that “Windows Phone is different to other smartphone platforms thanks to Live Tiles.”  I won’t comment on that one!

However, this is an entry-level smartphone and it isn’t designed for the North American or European markets. The Nokia Lumia 510 will be available in November starting with India and China, and followed closely by other Asia-Pacific countries and South America. Nokia estimates the retail price will be around USD 199, excluding taxes and subsidies.
