Never mind the fact that AT&T was recently ranked dead last by J.D. Powers & Associates in a network quality and performance survey. Well, no—if you're an AT&T subscriber, do mind that fact. But take a little solace in the fact that Ma Bell recently rolled out its new high-speed LTE network in Chicago and Atlanta, and that—surprise, surprise—it's actually fast. Very fast. 

Don't believe us? Check out the above video. Running on AT&T's new HTC Jetstream tablet, the network manages to hit download speeds of over 22Mbps, and upload speeds over 6Mbps. That will put its service nearly on par with Verizon's LTE network. Well, we hope.
