We just got a couple images from one of our Apple ninjas and it appears to show a compass option in one of the debugging menus. Our source says this is obviously for a built-in magnetometer in the upcoming iPhone hardware revision and with what’s already been reported, we’d have to agree.
Just in case you’re wondering, “A magnetometer is a scientific instrument used to measure the strength and/or direction of the magnetic field in the vicinity of the instrument.”
