The point of the presentation is not that GSM has been broken; it's to make it so blatantly, obviously, publicly broken that the public (i.e., corporate IT departments) will have to pay attention.
It seems likely that to the extent that things like the GSS-ProA suitcase interceptors crack A5/1, they do it with special-purpose hardware. A practical software attack is news.
