Earlier this month, we reported the existence of an affordable Lumia 510 handset which will arrive in the market soon. Nokia India has now confirmed the existence of this handset on their Facebook page with the message "610 - 100 = ? Stay tuned. Coming soon."
While the post has since been removed, it is clear that Nokia will continue to offer affordable Windows Phones to their users, with the device expected to be priced at just $150 without a contract.
In terms of design the Lumia 510 would greatly resemble the Nokia Lumia 610, but features a larger display which is always an added bonus. We are curious why this device is expected to run Windows Phone 7.8 which will loose developer support as most Windows Phone developers will now focus their attention on Windows Phone 8 instead.The device is reportedly headed to China first and we expect that it will also make its way to several immerging markets around the world. Currently there is no indication if Nokia plans to offer the Lumia 510 in the US or Europe.
