This seems like something of a throwback hack. [WilinNeofoxx] has built an audio modem interface for use with his Android phone. A program running on the Android device takes the accelerometer data and converts it into a 9600bps audio signal, kind of like a dial-up modem. His custom circuit board takes that sound in through the headphone jack and demodulates it for use on the serial port of a PC. This connection to controls a flight simulator using the G1’s motion sensors. In the video at the bottom of his post he unplugs the audio cable for a few seconds and you can hear the audio datastream coming from the phone. It’s pretty annoying so you might want to turn down those speakers before viewing it.
