That’s the question after a Twitter feed, @evleaks, posted a set of images early on Aug. 31. The first, it claimed, was of the “4.3-inch Nokia Lumia 820." While the second purported to show the “4.5-inch Nokia Lumia 920 with PureView.”
Corporate-sanctioned leaks are a fairly regular thing in the tech world, but they tend to follow well-defined patterns: a public-relations executive—wait, sorry, “unnamed source”—will email a journalist with an image of an upcoming device, for example, or a disgruntled former engineer will data-dump information onto their blog. Glossy publicity images originating from a new, relatively unknown Twitter feed is less common, although the Twitter feed in question has leaked other images in the past."
