According to the article I linked:
"According to the company, the built-in microphone that comes with the iPhone 3G and the headset microphone both have sound characteristics that make them suitable for measuring sound levels."
According to the website of the publisher:
"The iPhone's built-in and headset microphones exhibit a remarkably flat frequency response, making them suitable for basic sound level measurements."
They also note: "Even though default sensitivity values are included for the iPhone's built-in and headset microphones, for best results, SoundMeter should be calibrated before use. Sound levels may be off by 6 dB or more when using the default microphone sensitivity."
The company seems to specialize in fancy acoustic testing software, so I'm inclined to at least give them the benefit of the doubt that they have at least some clue as to what they're talking about.
