Rumor has it that the image above is the low end Nokia Lumia 510, This device recently passed certification in China. It is said to sport a 4inch display, with a 800MHz processor, 256MB RAM memory, WiFi enabled, 5MP camera and will run on the windows phone 7.8 update (due to roll out on existing Lumia phone in November). Seeing this was leaked in China and passed certification there, I think we can assume this is a CDMA device?
Here are more leaked images…
As you know the Lumia 610 is already on sale in the Asian markets and doing pretty well, and with the introduction of the Lumia 510, it seems Nokia plans to dominate the low end markets in that region with its low end windows phone.
