The above pic is rumored to be the Samsung Impulse 4G, and could very well be the first 4G LTE handset for AT&T. It's interesting that it looks an awful lot like the Samsung Droid Charge. Perhaps, it is just a re-badged Droid Charge built for AT&T. There were no specs details given with the pic, so there is no way to guess further, but we will keep our eye on this one for AT&T users.
