As iPhone Live! regulars know, I use a Blue Microphone Snowball for our podcast, so when they announced their 2nd generation, iPhone 3G/iPhone 3GS compatible Mikey, I was gravitationally pulled towards their booth for a quick look.
It's small, it plugs into the iPhone dock, and they also offer a free Blue Fire field-recorder app in the iTunes App Store [Free - iTunes link]
The 2nd gen Mikey should ship this spring. Check out the video after the break, and note: this was recorded using a pre-production unit of that very mic!
