This is the same phone that leaked in Microsoft's puzzling Windows Phone 7 ads, with the square corners and three-button bottom. With Microsoft's WP7 unveil slated for the 11th, we're sure HTC will be revealing all then.
It appears that the German site BestBoyz got their hands on some official press images, judging by the quality of them. I believe this is the first time we've seen the rear of the phone, which suggests it'll have a single LED flash and removable upper plate for SIM/microSD card insertion. But what is that silver button on the lower right-side of the phone? A camera button? If so, that's an addition that will make a lot of people happy. [BestBoyz — Thanks, Kamal!]
