Seems, GDR3 is already on 18% of Windows Phone 8 devices. It seems less, but the thing is, Lumia Black has been rolled out to only Lumia 925, 1020 and 625. So, seems WP8 device owners are really aware of the updates coming for their devices.
Second teaser says that top 12 Windows Phone devices are now from Nokia.
Third teaser doesn’t paint a rosy picture about Windows Phone sales in month of January. There has hardly been any change in % share of Windows Phone 8 as compared to Windows Phone 7 from December to January.
