The Federal Communications Commission has approved the previously announced HTC EVO 3D for the Sprint network with an interesting and unannounced spec. The FCC has confirmed that the EVO 3D supports 800MHz CDMA in the ESMR band. The ESMR 800MHz band is what Sprint uses for its iDEN network. Sprint eventually plans to transition the ESMR band from iDEN to CDMA as part of its expansive network improvement initiative. Once that transition is complete and Sprint ports its voice services to the ESMR spectrum, the HTC EVO 3D will be able to make use of it. Sprint's main CDMA network operates in the 1900MHz PCS band.
