All About Symbian regular Matt Radford is hosting the Carnival of the Mobilists this week, it's here at his All About iPhone blog. Carnival 125 is a bit of a cracker, actually, with discussion about whether content providers should pay the carriers for the data consumed by the end user, with a look at a huge new mobile-related craze from Japan, plus a detailed look at the implications of Google's Android (and the aforementioned Apple iPhone) for the rest of the smartphone industry.
