 CONT: The first time we see Wing take out his cellphone in a bar, he  was holding a Nokia 7610. Next, when he calls his girlfriends  number outside her apartment, he is holding a Nokia 6600. Soon  after, we see him holding his Nokia 7610 again. Just as he enters  his girlfriends apartment, he is using the Nokia 6600 again. From  then on, he just uses the 7610.
