OK, so this is the same Radio Shack that had that "rough launch date" of June 4 (which from the beginning looked like it was never going to happen). But a Radio Shack flyer is at least a little more official, insofar as these unofficial things go. And the flyer you see here says the HTC EVO 3D will be available June 24, which matches up with that not-before-June 23 vibe we've had going.
But to play devil's advocate, it could also be a Canary Trap on Radio Shack's part, or an early version that's subject to change -- you know how these things go. News at 11, folks.
