The Thunderbolt 4G is the first honest-to-goodness 4G phone on Verizon, the first LTE smartphone you can buy in the US. In other words, it's the fastest phone—connection-wise—that you can buy right now. And holy crap, is it fast.
It looks like the Verizon HTC ThunderBolt couldn't hide any longer. The ThunderBolt popped up (with the Inspire 4G) in an ad in the current edition of Rolling Stone. The ThunderBolt will probably be the first phone to have LTE.
