The question is quite logical and I do agree with Richard as well. Though a better answer lies in the fact that there can be a logic developed which would involve Service Book parsing and making use of system listeners to check the current coverage status.

I had attempted to make one such logic once in my project which worked for me. I had shared my findings and understanding about the concept in more detail at my blog post. May be you would like to check once.

Your question springs from an incorrect assumption. A Blackberry could be communicating over any or all of those channels simultaneously. In fact any application may as well. At any particular time you can determine if coverage is sufficient for one of those channels, or register a listener for notification of changing status using net.rim.device.api.system.CoverageInfo.
