Last December, we talked about a company (gomite) which designed a GPS module for the iPhone called LocoGPS. The same people have now designed a wireless module to do the same job and is expected to hit the market as soon as Summer 2008. Also called LocoGPS.
Since the bluetooth on iPhone is reserved for only wireless headset they actually used WiFi to transmit data between the GPS receiver and iPhone. To make this possible the GPS receiver integrates a processor, Wi-Fi antenna, and even a microSD card slot to store the maps.
