FavouriteContacts is a new tweak/app that is added to your iOS springboard and it gives you a quick, easy access to your favorite Address Book contacts to email, call or send a message in a hurry.
This list from which you choose your favourite contacts is based on your speed-dial contacts in the phone app by default. So, once you install FavouriteContacts, go to your contacts, add a favorite, and after respringing, it will appear in your new app.
Of course you`ll need a jailbreaken iOS device to install the widget. The app is available on cydia.
