The Samsung Z1 was released in India a month ago and has sold over 100,000 units since the last update. It has now found its way to the Amazon India site and is selling for 5,700 INR + 45 INR Delivery (Inclusive of taxes) for the white version, whilst the black one is 50 INR more. The unit only ships within India, so not the best solution for International buyers.
