we know that Windows Mobile 6.1 exists, we know that it's even available for
some devices already, even if not officially supported but so far we haven't
heard anything official from Microsoft and everybody including me expected an
official announcement during this year's Mobile World Congress. Sure, around
half of the new Windows Mobile devices showed here on the Mobile World Congress
are running Windows Mobile 6.1 already but there was not a single official word
from Microsoft on its press release.
Microsoft declined to comment the existence of Windows Mobile as well as it
wasn't commenting the availability.
So the best bet is that it's already available, most likely for ODM and OEMs
but for some reasons it wasn't announced today.
