Not sure, Calvin, but he could be referring to that applet that adds an option to the status area pop-up (you know, the pop-up you get when you press the status area) allowing you to switch between 2G-only, 3G-only or "dual mode" (which tries 3G whenever it cans, drops back to 2G when it can't get a 3G signal). Since that app is very easy to use and is accessible through the status are (meaning, changing modes is *really* fast), he probably wants to know if autodisconnect can check for whatever network settings that app applies. I mean, it's an add-on done with the "public" API (as in, using something that isn't exclusive to official Nokia code) so it should be possible to "read" which configuration is being used at the moment. Put another way.. If you can determine that the phone is working in "dual" mode (switching back and forth between 2G and 3G depending on signal quality for each mode), which I'd bet is how most people run it most of the time, then the "2G" option on autodisconnect would work as intended. *But* if you can determine the phone is *not* set to "dual" mode and has instead been configured by the user to run exclusively in 2G or 3G mode, then autodisconnect should ignore the 2G setting and just let the phone work in whatever mode the user has set it on. Gotta rush otherwise I'd test it right now with that app ("3G/2G/Dual Mode Selection Applet" is the one I'm using but I'm sure there's a bunch other that do the exact same thing). Don't know if you use it, if your 3G coverage is good enough you probably wouldn't have any use for it, but try it out and see what happens with each mode and autodisconnect's 2G option.
