Exposed: GPS for iPhone interview

I was able to catch up briefly with the PosiMotionteam and learned just a little bit more about their idea to bring an external GPS receiver data to the iPhone. Since Apple doesn’t seem to be freeing up bluetooth for anything but the headset and the SDK isn’t allowing software to talk through the dock, just how do you get GPS data into the phone? PosiMotion’s answer is via WiFi. Clever.
