Continuing its obsession with the number one, HTC has officially announced the First, an Android device with a bit more Facebook influence than most other smartphones we've used in the past -- including other handsets given preferential treatment from the social media network during the last four years. HTC's Peter Chou and AT&T's Ralph de la Vega took the stage at the event to announce the phone, which is the world's first Home-optimized device. It will be available on April 12th exclusively in the US on AT&T for just $99.Gallery: HTC First
