iPhone Delivers: Bigger Browsing Share Than Windows Mobile
I would like to see data about the data used -- with almost 100 million S60 Symbian users around [1], I find it hard to believe that there would be 9 times more people browsing on an iPhone than S60 device. (0.09% vs 0.01%)
For examle, user agent strings from browsers, at least on S60, are far from trivial to parse. And it would be easy to get skewed results based on the sites that are used to gather the data.

Seeing as how AT&T forces you into a data plan with the iPhone, these statistics make sense.
