Slow LTE buildout isn't news. Neither is LTE in general, for that matter. But with everyone muttering about the iPhone 5 having it, it's probably worth a quick glance at where it's actually available, before letting your idiot brother sign up for a wickad fast iPhone, knowing he won't get the speed increase for quite a while, maybe not before his contract is up. CNN did everyone a solid by making an interactive map of Verizon, Sprint, and AT&T (Other regional carriers also have LTE.)
That's the Verizon map up above, and you can see AT&T's and Sprint's decidedly less filled out maps over at CNN.
So, there you go. Nationwide LTE coverage—only not so nationwide. [CNN]
