Lumia 520

The Lumia 520 has remained the most popular smartphone in the Windows Phone ecosystem for well over a year, and now the AT&T no-contract version of the 4-inch device is on sale for rock bottom price of $29.

Both Amazon and the Microsoft Store website are selling the AT&T Lumia 520 for that price, which is $30 below its already bargain cost of $59. In July, Microsoft said that it had registered over 12 million activated Lumia 520 units, and with these sales prices we would imagine that number will continue to get bigger, even as successors such as the Lumia 635 and the Lumia 535 start to take away some of its market share.
