The HTC Evo V 4G is a variant of the HTC Evo 3D for Virgin Mobile. The Evo V 4G includes the same features of the Evo 3D including a 4.3 inch touch display, dual 5 megapixel cameras which are capable of capturing 3D photos or video, a 1.3 megapixel camera for video calls, 4G WiMAX connectivity, 4GB of internal storage which can be expanded through microSD and is powered by a 1.2 GHz dual-core processor.
What makes the device more appealing is that it has Android Ice Cream Sandwich (ICS) on board, but HTC has chosen to keep Sense 3.5 instead of the newer version 4.0 of the Sense UI which comes with newer ICS devices.
