I have Verizon's Facebook page Liked, so I always see stuff from them in my news feed. Something I've noticed: I don't think I've ever seen them advertise the Droid 4 except to announce it was released. Ever since then, they've just been pushing the Droid RAZR and the RAZR MAXX. I haven't seen ANYTHING about the Droid 4.
Why is Verizon so quiet about them? You'd think they'd be pushing them hard, advertising it as their first 4G LTE slider.
