This weekend I tried placing my iPhone 4S in a blackberry 9900 leather holster to see how it fit. Now when I try to use the compass or any app that uses the compass I always get prompted to calibrate it and have to do the figure 8 pattern for 10 seconds. I can be in the middle of an open field and always have to do this. I did not have to before. I tried rebooting the phone and a restore and it didn't resolve the issue. I don't know of anyway to degauss the phone.
Got a tip for us?

Warning. Placing iPhone 4/4S in case with magnet will destroy the compass!

If its being bumped around in your pocket with loads of little movements it is bound to lose its bearings. Thats why you need to calibrate it with a decent sized figure of 8 so it can tell which is its arse and which is its elbow.
Random data point: ipad2 compass function in Maps works fine and Apple themselves provides a magnetic cover using magnets in the ipad2 and in the cover.
@richard371: when you have the compass app open, does moving the magnetic case near/around the phone case affect the compass heading it shows if the phone remains sitting on a surface unmoving?

It worked after I tried the youtube tutorial, but it appears that i have to do it everytime I exit/enter the app, very annoying.

from the apple link I put earlier,
"After updating or restoring your device, you may notice that the recalibration alert appears more frequently. This is expected behavior, because the calibration database is being recreated. The frequency diminishes over time as you calibrate the device for various locations."

It seems to work ok but as soon as I exit and go back into it it tells me to recalibrate again. I assume the phone is magnetized permanently now. I can in the middle of a field and get this all the time now. FYI I am not using the Blackberry case anymore. it was only in there for about 15 seconds.
