If you were told the iPhone was one of the easiest phones in the world for a disabled person to use, you might spew your coffee. The thing has almost no physical keys! How would a blind person use it? It’s a phone that rings! How would a deaf person use it?

It’s pretty amazing (and it doubles the battery life).

You can also magnify the screen, reverse black for white (for better-contrast reading), set up custom vibrations for each person who might call you, and convert stereo music to mono (great if you’re deaf in one ear).
