When will the rest of the world catch on to this little jem, it's the way forward, over the air download charges are insulting the customers and forcing them to buy their content on-portal, ala vodalive, if the world went mobile-wifi things would change for the better, users would get richer content without the download costs.

Voice over IP on your mobile phone is just a natural step forward, how many networks don't want to go there though as they'll lose minutes. Scary part is how do they compensate for it?
