Had it confirmed to me in person by the CIO that they're redoing the website, although he was more specifically referring to the slow login times and dicey account information functions.
One day when I was on-site at Virgin's HQ near SFO, I saw people I knew from a mobile app development company signing in at reception. So while the two are not coupled, I wouldn't rule out a mobile app coming some day. They're at least taking meetings with those (crappy) companies.
