Lumia 510 is now available to order at official Nokia Shop in India in three colors Black, Red and White. The quoted official price is 10499 INR, which is 500 INR more than what Flipkart has quoted and subsequently went out of stock. But even the pricing of 10499 INR is good, considering the earlier expectations were around 11000 INR.
