economy - Smart internet marketing by Motorola

I was just scanning the material I could find by the Back Dorm Boys when I stumbled into this unbelievable clever piece of marketing by Motorola. At the end of this movie you see the guys picking up their mobile phones and Huang Yixin get a women on the line complaining about being neglected. That came back in this promotion for Motorola.
It fits all too nicely to have been done by the boys themselves (like the clear voice from the mobile phone is quite an achievement unless you have the equipment to mix it). Very nicely done, I must say.
