    I work in a "normal" office surrounded by lots of PCs and lights and overhead aircon ductings.
    We experimented with 3 new 3GS today, the compass'es pointed at three different directions in one instance. And when we place the 3 iphones side by side, sometimes they are in synch and sometimes they are not.

    So my question is: how much do you trust the compass?
    Is this only an inside-building behaviour?
    Outside the building the orientation seems ok.

    In such a room with a lot of magnetic fields that can happen.

    im in a field where i can check the accuracy of our compass to 'real compasses' multiple times per day/week (not that i do) but i occasionally do look.

    The compasses i check it against are either on an airplane, or on a boat. typically what i find is that its 25-40 degrees off. usually towards 25. I recall a time when i first got it where it was as bad as 45-90 degrees off.
