Woopsie! Looks like a graphic designer working with Verizon is about to have their wrist slapped as they've got a Motorola Droid X ad up promoting Google Maps voice guided feature - but with the wrong image on the screen. Take a close look and note that the nearby BlackBerry Storm2 is, indeed, running the correct version of Slacker radio.
Does this give a clue about Verizon's future with iPhone? I really really really doubt it. Doesn't mean it wont happen, but more than likely this was just a tiny mis-step.
