Which T-Mobile Ad Campaign is the Most Effective?

We discussed earlier today T-Mobiles latest ad campaign for their 4G MyTouch phone. The T-Mobile brand has had several different approaches in the past, from celebrity endorsements like Catherine Zeta Jones, to last years memorable flash mob at a train station. But in case you missed the live T-Mobile YouTube video "Welcome Home" last Thursday, passengers received the most welcoming arrival of all time at Heathrow airport. The brands slogan "Life's For Sharing" really stands true to their marketing strategy as you will most likely share these videos with others. What type of commercials do you think works best for the T-Mobile brand?
