I was doing some playing around today with the "Mode of Operation" page in phone settings with "DDTM mode" on/off and calling the phone while there is an active data connection as well as other things and found the following:

While in hybrid mode - everything works the way it should while on a EVDO tower but when it is on a 1X tower inbound phone calls work but DO NOT obey DDTM mode selection and no matter what calls will go to VM if there is an active data connection.

While in EVDO only mode:
Inbound phone calls work and obey DDTM mode selection.
SMS FAIL both in and outbound.

While in 1X only mode:
Inbound phone calls work but DO NOT obey DDTM mode selection and no matter what calls will go to VM if there is an active data connection.
SMS work both in and outbound.

Anyone else have similar experiences or any fixes to have SMS's work while in EVDO only or get inbound phone calls to work during an active data connection while in 1X only?
