I am from India, yesterday i signup for bing rewards by changing the region to US and earned till today 70 points, and i want to redeem them against windows phone card to purchase apps, my question is can i be able use those wp cards when i actually used them for purchasing the apps because i m from India and bing rewards isn't available here. So any body please tell me whether it is fruitfull to gain some more points or it is just waste of time for me because m in a region where bing rewards doesn't works.
Between i use the US region in my windows phone too, so will it help me when i purchasing app through the wp cards or it is also a waste to use US region??
