htc logoBGR.com sources have apparently confirmed that the HTC London event on September 1st we told you about yesterday is indeed to unveil new Windows Phone Mango devices.

While Android is HTC’s bread and butter of course, our source confirms that Microsoft’s latest Windows Phone OS, Mango, will be the star of the show this time around. We have heard HTC will specifically be unveiling the HTC Eternity, a Windows Phone with 3.7-inch display headed to AT&T, in addition to the HTC Omega, a 4.5-inch Mango phone that is headed to T-Mobile USA

Not conclusive by any means, but it ties in with reported Mango release timelines nicely.
