Today at Mobile World Congress, HTC announced the Desire S, a device that we've seen leaked numerous times as the HTC Saga. It brings a similar form factor, but has a slimmer, stronger design thanks to unibody construction. The specs aren't going to blow you away, let us warn you, but it looks like a worthy successor to the original. Like the current Desire, it has a 3.7" WVGA display; in the case of the Desire S, it's a Super LCD panel. It's packing a single core Qualcomm Snapdragon 1GHz with 768MB of RAM, 1.1GB of ROM, and a 1450mAh battery. The camera on the rear can record 720p video and 5MP photos. There's also a front-facing camera for video calls and portrait shots. Beyond that, it's packing an updated version of the Android Sense UI which brings some minor changes to the UI. Look for this device to land in Europe in Q2 2011.
