The HTC Desire HD (aka HTC Ace) was introduced in September 2010. It was, in most markets, the flagship of HTC until it was replaced by the new models, HTC Sensation and HTC Evo 3D. The device comes with a 4.3-inch display, aluminum housing, Android 2.3.5 Gingerbread and HTC Sense. A Snapdragon S2 processor with 1 GHz Qualcomm, 768 MB RAM, a 8 megapixel camera with LED flash and 1.5 gigabytes of internet memory (expandable with microSD) round out the technical details. It was the successor to the HTC Desire.
