I wouldn't blame it on "very low penetration of credit cards". Rather, the pricing was definitely on the higher side (rs.700 or thereabouts going by one of the posts above). Had they even put it on offer for Rs.200 or so, rather than for free, it would have still grossed well. Price it right, and I am sure there will be a huge audience ready to buy. Personally, when I was on Android, even with my ZTE Blade, I had ended up purchasing for more than Rs.1000 in total. Am on WP8 now, and have already spent about Rs.600 for apps/games.
