Ask HN: Where to find partners for building my first mobile app

Hello Ycombinator readers. I have a question. I want to build my first iPhone or Android App, but i have a hard time finding a partner for my idea. I asked a couple of my friends, they are software/web developers and they weren't interested. Should I keep asking people, or should I 1 ask people in my CS class ? 2 post an Ad at college, Craigslist? 3 ask people who or CS majors that my friends know?
