When I work in the Windows Mobile environment, I can use platform-specific libraries to establish a cell connection and verify its availability. I am new to the Rho world and have been unable to see how to accomplish this in a Rhomobile app. Am I just missing something obvious like "it just works"?
For Motorola devices you can get very specific for using WAN via the Network library. http://docs.rhomobile.com/rhoelements/network/
For general devices you can verify connectivity via the System APIs http://docs.rhomobile.com/rhodesapi/system-api/#getproperty
Hopes this helps
