Verizon’s inviting AT&T back into that age-old marketing war we were just talking about, and this time they’re dishing out blows about their 4G network. The ad was spotted inside of what looks to be a bus stop, but we can’t confirm that. And we honestly don’t care. What we care about is the fact that Verizon’s getting aggressive with AT&T, again, and T-Mobile and Sprint might find themselves caught up in the fire before too long. Question, though: why isn’t Verizon going after T-Mobile? T-Mobile uses the same type of network as AT&T which they claim is 4G. Is AT&T just an easier target because they haven’t been calling their HSPA+ network 4G and because they have no phones that take advantage of it? Let’s not forget that Verizon has yet to launch a 4G phone either. (Though I’m sure they’ll have no problem bragging about the speeds customers can get using their MiFi devices.) FIGHT!
