The folks over at BGR have just received some very interesting pictures from a “trusted source” who claims that it could be AT&T’s first 4G LTE phone. The device is made by Samsung and is called the Impulse 4G. Other than the images, no details have been released about the device but it does look a lot like the Samsung DROID Charge on Verizon so this could be AT&T’s equivalent of it. I’m not a fan of the case (picture after the break), especially the weird little circular bump sticking out, but the phone does look great. Stay tuned and we’ll keep you posted.
