I thought at&t 3G only has 3.6 mbps version as top speed. But last night I get these internet speed results on my iPhone 3GS. What is your AT&T speed? I'm in New York City, so I use Server New York, NY. You should change server closest to your location. But the point is these result is more than 3.6 mbps. Does AT&T already have 7.2Mbps 3G data in NYC?
