T-Mobile At It Again

T-Mobile is quickly becoming the Master of guerrilla/viral marketing. They've mob-danced in a Liverpool train station. Created a sing-a-long in Trafalgar Square. And now they're welcoming home international travelers at Heathrow Airport with an orchestral serenade. Terrific execution and a whole lot of fun, not only for the travelers, but for all of us online. Well played T-Mobile.
