Do all T-mobile USA 3.5G towers support 7Mb/s? If not, is there a web site that lists which T-mobile towers support 7Mb/s? I read on the net of people who get 2.5Mb/s download or better but I have never experienced anything better than 1.1Mb/s download in any place that I have tried (West Lafayette IN, Chicago IL, and Washington DC) even though all places show 3.5G with 5 bars on my N900.

While sometimes I get 1.1Mb/s download, most of the time I get far less (<200Kb/s), even when it shows 3.5G with 5 bars. I wonder if it is lack of availability of 7Mb/s towers, high traffic, throttling, or that I have my device misconfigured. I have even more plus and the "unlimited" data plan.
