magnet phones - how do they work?

My colleague's new mobile phone produces a weak magnetic effect. What's the science at work here?

My colleague recently got an HTC Mozart and we've noticed an interesting phenomenon: the top portion of the reverse side of the phone (image here
) is lightly magnetized. The bottom of the reverse side is not, and the magnetized area is where the external speaker, camera, flash and power button are located.
The force is far from refrigerator magnet-strong but is powerful enough to pick up staples and paper clips. The effect persists when the phone is charging and when it is not. We briefly removed the battery and it persisted then too.
We have some theories but we're not scientists by any stretch of the imagination
so I'm looking forward to hearing the hypotheses of more learned folks.
