I need a reliable function for Windows Mobile 6.1, which can turn on and off the phone module in the device. It must have one parameter - boolean - which indicates whether I want to switch on the module (true) or switch it off (false). It must be written in VB.NET CF 2.0 or 3.5 (not C#!) and working with my device, which is Intermec CN3e. It can use any .NET library to do its job, but solutions using free libraries will be preferred.
