One-touch dialing isn't a feature that's innate to the iPhone, but add-ons like FaceCall make it possible. Turning a phone contact into an icon takes a few steps, though with clear direction, the set-up is surprisingly smooth. You'll be able to use a photo from the contact list or the camera roll as your icon image; if there are none, FaceCall will let you snap a fresh one from the application itself. After that, FaceCall's servers do the rest, leaving you unlimited new icons to position on your home screen. If you would only create a single icon, you may find the app too frivolous to justify the cost, but those likely to create a small directory of contacts will appreciate the personalized speed dial.
