The hot rumour doing the rounds right now is that Microsoft is lining up the long-awaited Mango update to Windows Phone 7 for a surprise launch on September 1.
Apparently multiple sources in the know have confirmed as much, though it seems someone forgot to tell Microsoft VP and Windows Phone boss Joe Belfiore, as he's just dismissed the rumours as just that.
The story first emerged when Pocket-lint quoted “multiple trusted sources” in dropping the September 1 bombshell. The logic, it seems, is that Microsoft could then ride the wave of publicity through the IFA technology show, which kicks off in Berlin the next day, and get Mango up and running before the next iPhone arrives to hog the limelight.
But Belfiore has played down the story, with a single, to-the-point tweet: "Sept 1? Just a rumor."
Of course, that's not quite a flat denial either, so looks like we may just have to wait and see.
