The HTC Sensation was introduced to the world today and several videos have shown up on YouTube in conjunction with the announcement of the latest handset from the popular Android phone manufacturer. Among the crop you will find the first-look video we already saw leaked ahead of the device’s announcement, the introduction video shown at the press event, and a quick overview from the folks at Three UK. It is worth noting that T-Mobile also posted the first-look video as they will receive the handset under the name Sensation 4G.
