HTC this morning made its presence felt at Mobile World Congress by launching multiple smartphones, including its new Android 2.1 flagship. Previously known as the Bravo, the Desire becomes HTC's version of the Nexus One without Google branding. It gets an upgraded HTC Sense with a unique home screen look known as "helicopter view:" somewhat like Apple's Exposé, a pinch gesture at a home screen shows all home screens at once to jump quickly to one of them.
