Unfortunately, the iPhone 4s's microphone distorts as high levels like concerts where the iPhone 4's didn't. I guess that's what you give up for 1080p video. Anyways, I have been waiting for Mikey's iPhone 4 microphone, but they have seemed to abandon the idea and the only one available is for iPhone 3GS and before. My main idea is to record live music with this microphone. Is there anything out there? I've used the Brando Mic: http://shop.brando.com/flexible-mini-capsule-microphone-for-iphone-3g-s_p03552c0202d033.html And it's terrible.
