Nonsense. If the FCC declared that all cell phones would have to use a single standard battery that would not be open but it would foster interoperability and would increase competition in the battery market. If the FCC declared that cell phones could design their own batteries that would be open but it would mean that your N900 battery could not be used by your Blackberry and your iPhone battery could not be replaced at all. Don't confuse open as in "open source" with open as in "open markets". The US regulators decided that they didn't want to choose between the Japanese CDMA and the European GSM so they let the open market choose. The problem is that it hasn't chosen yet and we still have both types of networks.
