Nokia :: N900 Wakes Up In Presence Of Magnet

I was given a case for my n900 as a gift. I found that every time I put the n900 into the case, it would wake up. I would put it to sleep with the spring loaded switch on the side, but no matter how gingerly I put it into the case it would keep waking up. It then occurred to me to put it into the case backwards, where upon it did not wake up.

The case basically has a felt type liner and a flap which is held closed with magnets in the flap and the front of the case. I have confirmed that both pieces are magnetized. I further discovered that if I run the front face of the n900 against either the flap or the front face of the case, the n900 will wake up.

Simply touching the face of the n900 to a magnet is not sufficient, it must be rubbed or passed in close proximity to the magnet, which I presume is then inducing a current some place that causes the n900 to wake up.I don't know if it is any more of a problem than to tell the case manufacturers not to use magnets, or at least not use them where they can be in close proximity to the face of the n900. So I am passing this along as a heads up when looking into getting a case, and where hopefully someone with more technical knowledge of the inner workings of the n900 might be able to elaborate on this.
