We don’t need anymore proof, but hey why not, this is getting fun. The eagle eyed scouts over at The iPhone Spot, have spotted (go figure) a tweet from @Verizon, originating from the Twitter iPhone app.

Now I don’t know about you, but something tells me that Verizon employee responsible for the Twitter account isn’t using an iPhone on AT&T’s network. You gotta admire the subtlety.

Incoming announcement tomorrow, folks.
