Do more with Contacts.

Contacts on iPhone is more than just a list of names and numbers. Tap a contact's address and iPhone automatically launches the Maps application so you can get directions. Add photos as part of your contact information and see your friends' faces every time they call. Scroll through Contacts with a flick, or search to find a specific name fast.

Multitask with a tap.

With iPhone, you can do more than one thing at a time. While you’re on a call, you can check your Calendar, do a quick Google search, even send an MMS message.^* Or you can switch between calls, merge calls, or add up to five callers to create an instant conference call.
