Nokia's Lumia 510 was toting Mango when we saw it last, but it seems the affordable smartphone will be hitting Indian stores with Windows Phone 7.8 instead. The new iteration, which is starting to filter down to other Lumia handsets, boasts a smorgasbord of new goods including resizable home screen tiles and 20 accent colors, with Espoo likely to add a few Lumia-specific features such as an enhanced set of camera lenses and improved contact sharing. While the lure of something lurking between WP7.8 and the more child-friendly version 8 could spice up the deal further, budget-minded Indian customers coveting a newer Windows Phone operating system might not have to wait till the New Year.
