This is the liberator limo, it goes around Madrid promoting the services of Liberalia, a company that unlocks all the phones that operators provide lock so you don´t go to their competition. Personally, I am happy that this has not been made ilegal in Spain. I believe that handset subsidies distort the mobile market and lead to a lack of competition.
Same happens in the States. For example, when I bought my iPhone, one of the things I criticized the most was that it is locked to use it only with AT&T. That is why I am happy to find out that George Hotz (17 years old from New Jersey) figured out how to unlock the iPhone and use it with other companies. The hack seems to be complicated though, and requires techie skills since missteps may result in the iPhone becoming useless.
