Samsung Impulse 4G to lead AT&T's 4G LTE charge?

Could the above shot be the first 4G LTE smartphone for AT&T? BGR thinks it just might be. The site nabbed a shot of what purports to be the Samsung Impulse 4G, which may grab that distinction on its release. That's about all we're getting in the way of details on this Droid Charge-esque device at the moment. Hopefully the screen of truth will be pulled back even further in the near future.
