Call Forwarding (GSM Part)

[PapaDocta]

The call forwarding option is not showing on the phone settings.. so i edited the register to show it there and it did.. now when i click on call forwarding and choose get settings i get this error message right away:
"Network Error
Cannot read settings from the network. Try viewing settings later, or disconnect data connection and try again"

there is no connection active or anything.. just can't get into the settings!

any help would be appreciated..
