We will not report 'CS' as a supported mode every time '2G' is supported. This actually was forcing all plugins to handle a 'CS' fallback when they didn't have CS-specific mode setup. So, to simplify things, we will only report 'CS' as supported for those plugins which actually allow to select 'CS' mode (e.g. the 'wavecom' plugin).
