Detecting movement with an iphone
<p>Can the iphone detect its movement in terms of distance? </p>

<p>Would one be able to use a built in function on an iphone to determine the distance the phone has moved so that the speed of movement can be calculated?</p>

<p>Basically my question is</p>

<p>can an iphone detect its position and distance moved without using the gps?</p>

<p>thanks</p>
