Hi, I'm currently building some application-tests for my Iphone project where I would like to automate the displaying of all view controllers step by step.

I know Flash doesn't work on the iPhone OS, but is there a way to get this type of mp3 player to work on an iPhone? I'm thinking maybe a javascript mp3 player. What I would ultimately want is to replace my flash mp3 pla...
