I have the macbook pro that came out early 2011, and I have had the weirdest thing happen. Basically I can set my iPhone 4 on the left hand side of the trackpad, like lay it on my computer and it will make it look like I put the computer to sleep. It makes the screen go black, and It takes a second to restart just like when you close and open a macbook. Its really strange because It only does it on the left hand side, not the side with the hard drive. Anyone else have this happen?
