Is this app compatible with the 3G/2G/Dual Mode Selection Applet?

I have both installed and on AutoDisconnect I have the following settings: when active [always], auto-switch 2G/3G [Dual - switch lasts 4"]. I have the 3G/2G/Dual Mode Selection Applet set to GSM.

I expect the behaviour to be that AutoDisconnect switches to 3G mode when an internet connection is required. However, it seems the phone remains in 2G mode.

It seems the 3G/2G/Dual Mode Selection Applet is over-riding the auto-switcher function of AutoDisconnect. Should I therefore only use AutoDisconnect, or does anyone have a way around this?
