Android Central recently picked up on an interesting advertisement in Sprint’s Playbook. Along with the fact that it’s advertising the HTC EVO 3D, the headline of the ad mentions a “Fourth Week of June” release date. There’s nothing to say, except that EVO lovers might want to get ready for some 3D next month. We have to mention that this is just speculation for now. Until we get confirmation, the Evo 3D is as good as a concept. Still, Sprint seems to be more than ready to release this beast of a device.
