Logan figured out long ago how to turn on my iPhone - just push the round button at the bottom of the phone. Sometimes he could also slide the bar at the bottom to actually get to the apps. Usually it was just coincidence that he could slide it, though. Today, he mastered that. And also figured out how to "search" my phone. Here's a short video with his demonstration. The next one is the first one I took, but it's a minute and a half and not everyone is as interested as I am - so I'm posting both for you to choose.
