Microsoft finally offered up some concrete numbers on at least one Windows Phone device as the company revealed that the budget-themed Nokia Lumia 520 has so far registered over 12 million activations



From WPCentral:

While third party data had already strongly suggested that the Lumia 520, and its T-Mobile variant the 521, have been the most successful Windows Phone device in terms of shipped units, the specific activation numbers revealed today by Microsoft chief operating officer Kevin Turner finally give a real idea of how successful the budget priced phone has been since its launch over a year ago.

Turner, who revealed the activation numbers as part of his Worldwide Partner Conference keynote speech, said today that the Lumia 520 is the best selling phone in its price range worldwide. Microsoft is now selling the phone as a first party hardware device thanks to the company acquiring Nokia's devices and services division in late April.
