I think that GG may be missing a trick; what about having an offer in place for music fans?
For example goodybags with less minutes and texts and perhaps a free song download.
Or even for that matter what about film buffs? same idea but maybe with a free movie to stream.
Again sports fans could maybe watch one live football "or any other sport" game as part of a goodybag.
I know certain companies have partnerships; i.e. virgin and netflix,
What about something along that line where you can get more than calls, texts and browing; make your mobile into an entertainment device.
Just a thought.
