I listened to about 5 minutes.
You have a good playful vibe, a nice deep voice, and a sexy accent.
But that interaction was waaay too long. I've no idea why you zeroed in on these non-seductive topics like a weird story about your hate for the iPhone 4 and even going into political topics like war (absolute taboo for cold approach) which she told you she didn't want to talk about.
My advice is to keep the interaction short (5-10 minutes max), focused on the girl, getting her qualifying, building some intrigue, creating a time constraint, and exit with a sense of mystery so that she feels like she actually wants to see you again. This interaction sounds more like she was just humoring you because she had nothing else to do.
