Nokia launches budget Lumia 510 Windows Phone 75, 4inch display and 5megapixel camera

Confirming all those rumors we've been hearing, Nokia has officially taken the wraps off its latest budget smartphone, the Lumia 510 -- slotting it somewhere between the Asha range and the Lumia 610. With the notable exception of the 4-inch (480 x 800) screen, which is a tad larger than its slightly more accomplished Windows Phone sibling, the other specs are very much in line with its low-cost stance: there's a single 5-megapixel shooter at the back (no front-facer), a lowly 800MHz Qualcomm processor, 256MB RAM and 4GB of non-expandable storage. We'll be bringing you further details as the story unfolds. In terms of the OS, it'll ship with WP Mango but we're told it will be upgraded to Windows Phone 7.8 at some point in the future.
