6720 Classic CSD/HSCSD is not working.
We tested this extensively on the device we got.
The Forum Nokia Device Specification info mentions that 6720 Classic includes support for CSD/HSCSD.
The Firmware info shows...
SW Version: 012.008
SW VersionDate: 22-Jun-2009
Custom Version: 012.008.C12.01
Customer VersionDate: 22-Jun-2009
Language Set: 20.01
Can anyone help with this?
