What is the focal length of the iPhone camera?

More importantly, what is the equivalent focal length relative to a 35mm film camera?
I have an iPhone 3G. Is the camera focal length different for the newer iPhones?

I'm guessing that it's different from the iPhone 4 one. But I don't have those details on hands, can't speculate on the iPhone 4 focal length.
