I did find at least one picture used in the campaign which was under CC-BY-SA (the best of the CC licences from a free culture perspective) so now the Virgin Mobile logo is indeed available under CC-BY-SA (or a compatible alternative). The logo remains protected by trademark of course.
I'm afraid it does not. I think including the picture doesn't make the ad CC-BY-SA; rather, it makes the ad a copyright violation.
