Thanks !
Especially for the dual mode version. I don't use 3G only anymore since I only use cellular network when moving (wifi when at home/work), and I want to be able to connect to the internet even when the only available network is 2.5G, but still benefit from 3G/3.5G speed when it's available.

regarding the three-mode switching, that could need one less click if there were 3 small buttons/widgets : 3G, 2G, dual, with coloring of the selected parameter, instead of only one only showing the current parameter used and switching to the other when clicked.
