This registry hack used to work with my Touch Pro, but does not with the Touch Pro 2. I'm wondering if there is another setting somewhere needed to unhide the Mode of Operation?

Enable hidden option of "Mode of Operation"
HKLM\SOFTWARE\OEM\PhoneSetting

Change the option HiddenModeOperationPage from 1 to 0

Then go to Phone/menu/option/service/and check in the list, "Mode of Operation" should be at the bottom. You have 3 choices, Hybrid, EVDO, and 1X.
Once you have checked the box and hit ok. You can switch back and forth without having to soft reset.
