WMPowerUser has published figures on the number of new Windows Phone 7 Facebook integration. Between the 11th and 25th of November (2011) there was a sharp increase of 100,000 accounts. WMPowerUser also claims that according to their estimated conversion figure this corresponds to a real world sales figure of 600,000 devices. Bear in mind that these are estimates. However, this would tie in with the release of the HTC Titan, HTC Radar, and the Lumia 800. To keep things in scale, also recall that 550,000 Android handsets are released daily; it is early days for Windows Phone though.
