You have to love the last days leading up to a major event like Mobile World Congress, because the rumor mill just doesn’t stop. The focus of this particular whisper is Nokia’s Lumia series, which according to Reuters should have at least two new members before the show is over. Its sources indicate that the oft-rumored global version of the Lumia 900 is go (AT&T’s model shown above), as well as a lower-end Lumia 610. All of us who crave the deeper details are still left in the dark about what we can expect on these devices, but it does give us a heckuva lot more to look forward to next week.
