HTC HD2 delivers an experience your senses have been waiting for. The unprecedented 4.3-inch pixel-packed display is stunning. The world’s first capacitive touch technology on a Windows® phone along with 1 GHz processing power ensure a smooth and lightning-fast response to the lightest touch of your finger.
Most importantly, it is our first Windows Phone to embody HTC Sense™ - a holistic experience that focuses on making phones work in the most intuitive way. HTC Sense is based on three core principles – make it mine, stay close, and discover the unexpected, htc official.
