Any
contact you connect with regularly is a good candidate for pinning to
the Start screen. Pinning is the smartphone equivalent of speed dial: It
lets you call or text that person with just two taps.
1. Pin a Contact
On the Start screen, tap People.
Flick to All, find the person you want to pin, and tap their name.
Tap Pin.
Tip:
You can also pin a contact to Start by pressing and holding the person’s name in the People hub, then tapping Pin To Start.
