I need help. I've tested on iPhone 3G, 3GS. The app should work on 2nd and 3rd gen iPod touch, but I'm getting the odd reports of no audio. You need an external mic on these devices. I would LOVE to get some constructive feedback, instead of a crazy mix of 1 star and 5 star ratings. Anybody got a minute to try it? Free app. http://itunes.apple.com/gb/app/voice-changer-plus/id339440515?mt=8 Thanks Dave
