Sprint customers can now pre-order their HTC EVO 3D and EVO View 4G tablet. The carrier has confirmed that you can reserve WiMAX device by visiting Sprint owned retail store and plucking down $50. No words yet on when you will be getting the device in your hands. It is also taking the names for View 4G tablet, and like the 3D, that $50 deposit can be used to take bite out of a 2D handset.
