SpringDial puts speed dials of your contacts on the SpringBoard of a jailbroken iPhone. The advantage of this is over using the Webclip method is that it is more of a true speed dial. Safari doesn’t have to load, and you are not asked to confirm the call. If you happen to have a photo for the contact in your Address Book, then it is what is used as the icon for the contact.

The easiest way to install it is to add the repo http://i.mineshaftgap.net/
