According to newly released Facebook data, there’s been 4.2 million Window Phone devices sold since October.
Steve Ballmer told us recently that Windows Phone devices were selling four times more than there were in 2011, which has also been confirmed by Facebook data.
Using the number of Monthly Active Facebook users as a guide, we can see around 627,000 MAU of the built-in Facebook app has been added since the 1st October 2012, the start of the quarter. Last year over the same period less than 150,000 was added by the 15th December.
Last year according to Gartner, who claims to measure units actually sold to end users rather than shipments, said 2.759 million Windows Phones were sold in Q4 2011. The data suggests already 7 million Windows Phones were sold so far this quarter, and we may finally be heading to a + 10 million Windows Phone quarter.
