An iPhone on Verizon rumor? It's about that time again, so here we go. This time, though, it's not coming from some unknown source somewhere, but instead coming right from Verizon. At least, Verizon's Careers Twitter account. And, what makes it interesting, or perhaps nothing at all, is the fact that Verizon hasn't pulled the tweet (yet). It's still there, ready for anyone to see and start their speculation. Does it mean, beyond a shadow of a doubt, that an iPhone is coming to Verizon? Well, you be the judge.
