I have a Nokia 6280 which is mostly kept in a good quality leather pouch with a magetic clip...the interesting thing is that everytime I put it in the keypad automatically unlocks and everytime i put it in, or take it out, the screen lights up? What gives? I am not touching any buttons. It does not seem to happen when it put it in/take it out fast? Magnetic field? Friction? Bad/good/indifferent for phone/screen?
