The finest Android phone we've seen so far, the Samsung Galaxy S II isn't just a competitor to the current iPhone. It competes with the next iPhone. The Galaxy S II is the fastest Android device we've ever tested, with the best screen, the best camera, and the latest version of Android software. It's a pity that few people in the U.S. will buy it, because it's only available unlocked, with no carrier subsidies, for $799. That's simply too high a price in a nation where people are used to buying top-of-the-line smartphones for $199. Click on through for our full review of the Galaxy S II.
