Pull down on the iOS 7 home screen and Spotlight reveals an empty text field titled "Search iPhone". While this can be a helpful feature to find something in a hurry, developer DarkMalloc had another idea. Why not make the Spotlight screen even more useful by adding favorite contacts into the mix?
Jailbreakers can grab the tweak QuickContacts for $1.99 and do just that. Once installed, there are no options to configure. The tweak simply adds four contact shortcuts directly to the Spotlight search screen. Pull down on the home screen and the contacts are revealed, then swipe from left to right if you need to use the Search iPhone field.
