Announced and demonstrated at the CTIA 2010, the Galaxy S is Samsung's first Android device featuring its own 1GHz Cortex-A8 based ARM application processor named "Hummingbird" (labeled as "Apple A4" in the iPad and iPhone 4) which also integrates hardware graphics acceleration (PowerVR SGX540 core). Being a rather large smartphone, it comes with a 4-inch Super-AMOLED screen and an Android skin called "Smart Life" atop Android version 2.1. It can be paired with an optionally available "Home Cradle" for use as a digital photo frame, table clock, calendar, and music station. Samsung is targeting 110 countries in North America, Latin America, Australia, and Asia. In the U.S., the Galaxy S is launched on all four national carriers: T-Mobile Vibrant, Verizon Fascinate, Sprint Epic 4G, and AT&T Captivate. It is also announced to be available on the regional carrier U.S. Cellular.
