The iPhone’s display is capable of switching automatically from portrait to landscape mode when you rotate it. So you should have a dock that allows you to view it either way. Sadly most docks are oriented for the vertical portrait mode.
Not this one made by Steven Combs. Steven can go both ways. Rather, his iPhone can. This dock lets him rotate his iPhone and better still, it’s made from gray, black, and white Legos. Instead of buying an expensive rotating dock, why not just do what Steve did?
