HTC has something up its sleeves this September.

They have scheduled a September event in London for the launch of a particular device.

Judging from the silhouette of the device in question, it is likely to the HTC Desire HD/HTC Ace which had a brief video walkthrough which can be accessed via link.

This device is similar to the HTC Evo 4G, the first Wimax enabled phone which is a United States only device. The HTC Desire HD/Ace is reported to have a 4.3 inch screen with an 8 megapixel camera with a dual LED flash. It’s a Android 2.2 device and well, it looks like another winner for HTC.

All will be revealed in September.
