sorry it is Settings ( \Windows\ctlpnl.exe cplmain,20,2)
Parameters is a bad translate from me from French
I repeat to be sure of your understanding:
Can you display Operator's name (in the first Page)
and allow tapping on it to run the settings about Network for the Phone (I live between France and Belgium and I need to change the Network 3-4 times a day)
better : if possible to customize ourselves the function to run (allowing a command with parameters)
like dagosjt said too.
