AT&T today landed a surprise win in a new test of 3G performance in the US. The carrier had both the fastest average download speeds, at 1.4Mbps, and the fastest uploads, at 773Kbps. Both were major improvements and were as much as 84 percent faster than what was seen a year earlier. T-Mobile and Verizon were only periodically able to crest 1Mbps while Sprint would only come close to the mark.
