we told you how India's smartphone market soared 48% in 2012. More importantly for the Nokia Lumia 520, Windows Phone 8 had a 5.4% share of the Indian smartphone market in the fourth quarter, topping the percentage of the Indian smartphone market that belonged to the Apple iPhone. With the popularity of Microsoft's mobile platform in the country, and the affordability of the Nokia Lumia 520, the phone should do quite well in India.
The Nokia Lumia 520 is going to be available sometime in the first week of this month and yes, a variant of the phone is going to be available for T-Mobile as the Nokia Lumia 521. While there is no word on how T-Mobile is going to price the phone, it could go for free with a signed two-year pact.
