TechCrunch: “In theory, I’m right there with you. The thought of a truly open mobile operating system is very appealing. The problem is that in practice, that’s just simply not the reality of the situation. Maybe if Google had their way, the system would be truly open. But they don’t. Sadly, they have to deal with a very big roadblock: the carriers.”
Leave it to the carriers to ruin a good thing. As others have said, this could be one big reason Verizon doesn’t have the iPhone.
