The Nokia 5140 has a compass that works in the conventional method, by reading the Earth's magnetic field vectors.<br><br><a href="http://europe.nokia.com/A4144100">http://europe.nokia.com/A4144100</a><br><br>See the user guides, which are made with Flash... :o

Hi!<br><br>I was thinking about the same problem. But once I have seen a working<br>compass in a phone already (we have crossed thick woods following the<br>compass :-) - it was a friend's phone, I think a Nokia). So it is not
