iPhone 4 with Shure SM58 External Microphone

Visit the articles section on Life is a Prayer.com for more information - In this video, I demonstrate using the iPhone 4 with an external Shure SM58 dynamic microphone, through my iMac (using a Griffin iMic to get the mic into the computer). I'm using a KVConnection adapter to get the line-level output of the iMac down to a usable input on the iPhone.
