I read through the iPhone 5s tips and learned I wasn't really maximizing what it can do. For instance, I didn't even know the phone could take a panorama shot and like the calendar view when switching to landscape.
Some of the items did not work such as viewing the time stamps of IMs which I would like to see sometimes. I haven't upgraded to the new OS so perhaps tht is why. (My excuse: I just moved cross country to MN with the family.)
