Sprint is a US Version and has the FM Radio. It is the only US G2 that can use NextRadio, which requires the FM hardware. IDK about any other carriers, other than I know ATT and VZW don't.
All LG G3s have FM radios in them. Verizon has decided to disable the radio, probably to get us to switch to streaming radio and use more data. You can even download the radio apk online, but it won't work. Sucks big time.
Of course most customers either use wi-fi and/or have unlimited data so if that is part of some evil plan to make more revenue it's kind of dumb. Since I have wi-fi I can stream hundreds of hours of music a month without using any of Verizon data. Also you can download music to your device so you're not using data that way either if you're in a non wifi area.
