<pre wrap="">I think timing would be a challenge with the magnetometer. My game
Galactic Patrol: Zap GPS uses the compass and gravity sensors. You
position the phone to shoot down GPS satellites. The sensors don't
respond all that quickly on my G1 phone and the response is pretty
sloppy and dependent on what else is running on the phone. They are
useful for their purpose but transferring signals isn't one of those
purposes.

I think Scott was talking about this:

Reading the fine article reveals that the guy was able to get about
7bps... *bits* per second. Pretty low baud rate. How long is the
typical APRS message? A quick glance at aprs.fi shows at least one
message from MB7UIK that is 131 characters long. That's about 19
seconds to transfer over the magnetometer.
Still, kind of cool.
