The commercial is about a couple driving around the country, and the girl sitting at the pessenger seat keeps using her black Lumia 900 to do stuffs. First of all I think this is the first Windows Phone I've seen on AT&T's non-phone specific commercial. Second, it was actually a bit difficult to tell which phone she uses, unlike that one they shows the basketball game. Was it just I didn't start paying attention at the begining? Or AT&T really did it implicitly?
