I want to use screenflow to record me playing games on my mac for youtube. But i dont have a snowball or yeti microphone o anything like that. And i gave up on trying to record things from an xbox 360. So i have an iphone 3g and I know it has voice memos on it where I can record my voice and put it in itunes and use it, but can I use it to record my voice WHILE im playing the game? or is there an app or something? Please help!
