But until now the device was not available in the US but now Sony Ericsson has come to its senses and has launched the device stateside in a SIM-free version. The unlocked Xperia Arc will set you back by $600, which is fair considering the specs of the device but if you ask us you should rather wait for the Galaxy S II, unless you have a thing for curved backs or Sony Ericsson.
