Eric Raymond has been writing almost exclusively, of late, about the future of cell phones. Particularly as it relates to Android versus iOS and which one will ultimately become the dominant mobile OS. Along the way, he’s noted a couple of times that he believes that smartphones will ultimately lead to cellular providers becoming basic “bit haulers.” As I read this post from John Gruber about Facetime on the iPhone 4, I’m wondering if the pieces aren’t coming into place that might force this issue in the nearer term.
