I don't use an iPhone. I gave my mother one because they're pretty darn simple to use. One small thing that's kind of a pain with the iPhone is the connector. It's completely symmetrical so without being able to see it, it's impossible to tell which way is up. My mom figured out a neat trick to always be able to plug her iPhone in without needing to be able to see it. Simply take some nail polish and make a dab or three on the top face of the connector! Now you'll have no trouble charging your phone in a dark room.
