Addial helps you add contacts or call phone numbers directly from the Notifications Center

  Additionally is a tweak released during this night in Cydia, and with its help we can greatly simplify the process of adding a contact to the contact book or calling a phone number. The tweak implements in Notification Center two widgets, one that opens the interface for adding a contact to the contact book, the other that opens the Phone application dialer. The two widgets are activated from the menu Settings>Notifications of iOS and will be activated together.

Addial (pronounced as ad-yal) is a free Notification Center widget that allows you to add a new contact or just dial a phone number. It has a very native UI and look. You can also localize Addial by going into Settings > Addial. It's simple. Don't forget to Enable it from Settings > Notifications > Additional after you've installed it.

  Additionally it is available for free in the repo ModMyi al Cydia.
