license free

Purchased the Baofeng BF-888S and can't find much information on the frequencies that the radio came programed with, this was purchased through Amazon and I really would like to know if these radios are license free with the programming that came in them and can be used in the U.S.

Hi Is it possible to change the frequencies pre-programmed into these radios, or change remove the tones, PL, Ctss etc again pre-programmed into these radio, if software is required what software version is it ?. Thanks in advance David
