I just got the new iPad Mini and in lieu of giving Apple $40 for their overpriced Smart Cover, I was going to create one. In previous iPads, the lock/unlock function of the smart cover was activated by a magnetic sensor to the right of the screen. When the cover closed a small magnet in the cover would activate this sensor and the screen would go off. To find the location of this sensor, all you would have to do is drag a small magnet (of the correct polarity) along the right side of the screen and when it hit a certain point the screen would automatically go off. Here is the mystery: with my new iPad Mini, I've dragged a magnet all along the right bezel, using both polarities, and nothing at all activates the lock/unlock function. It makes me wonder what sort of secret sensor Apple is using this time around for their new iPad Mini Smart Cover. Anyone else had a chance to test this?
