It might be a good idea to use a single gboolean, or better yet an enum
here instead. There's no point to waste 8 bytes when a single byte can do.

First of all, this really belongs in atutil as a convenience function.
Second, why don't we fail on the obvious condition that neither CDMA nor
GSM is detected?
