I think this is correct. When I had 2.2, speed was always 800 Mhz, and there were 4 speeds available. Now with 2.3 on an HD104, there are 3 available speeds: 160, 400 and 800 Mhz. In about 10 minutes running (most of them downloading and installing Android System Info and other diagnostics software), 12% were on 160, 43% on 400 and 45% on 800 Mhz. I also used Quick System Info Pro to have speed and CPU load information on taskbar. According to it, most of time the screen is on with no programs running gives me a speed of 400 Mhz, ~30% CPU load. Without a sim card.
