T-Mobile has completely upgraded its entire 3G network to HSPA 7.2Mbps today according to Phonescoop. I busted out my Nokia N900 to test the speeds here in New York City and I was able to get about 6Mbps downloads and at least 1Mbps uploads!

Here are three consecutive speed tests from Speedtest.net. Yes… the Nokia N900 can actually run that website in the web browser unlike most, if not all, current phones in the market.

Does this mean AT&T have to stop saying they have the nation’s fastest 3G network?
