bought the seidio holster and was messing around with the phone going in and out and noticed it was going to an all black screen (with clock) as it entered holster. The seidio keyone holster/clip has a magnet in it that puts the phone to sleep. I took a magnet to the screen and found the spot. It's on the left side of the screen, halfway up. Thought this was interesting, old school 'berry feature
