Chicago was the first city to get AT&T's new LTE network and a new video has been posted showing off some of the expected speeds. This video was recorded at a live show, where AT&T took up a Jetstream tablet and used Speedtest.net to show off just how fast their new network is. The results were somewhere near 22Mbps down, while upload speeds climbed above 6Mbps. If you want to compare it to Verizon, its not even close; Verizon typically gives me results around 36 down, and 5 up. Take this news however you want, but this goes to show that 3G is slowly becoming a thing of the past.
