It's technically called "Build Windows." But this year, the biggest news coming out of Microsoft's annual developer conference might not have much to do with Windows at all.

Might we catch a glimpse of some new phones ahead of tonight's Nokia shindig? Your guess is as good as ours, which means you'll want to follow our liveblog as we give you the blow-by-blow.
