I used three examples. The first Real Madrid, that already has bluetooth in the Santiago Bernabéu. you can receive "at live", the best moments of the match, including in other angles. The Bayern München also already has this service, and in the Olympic Games of Pequim, Coca-cola offered this same benefit for the public.
The mobile communication is one thing that still can be much more explored and i realize as much we still can use it. But i am not the only one, Samsung started a new campaign "54M5UN6", in the Palmeira's t-shirts. The users could talk to each other trough the program Scrapy 459.
What else they a re going to do, i don't know, but congratulations 54M5UN6 by the great idea. A great team, deserve a great promotion.
