FaceTime
Just like the Send Message button, the FaceTime button will launch its respective app and attempt to make a video call to your contact. I cover FaceTime in Chapter 10. There are some caveats about using this service that you’ll need to know before using it, so just know that if you and your contact both have devices that support FaceTime (iPhone, iPad, iPod touch, iPad mini, Mac OS), you can make video calls and see and speak to one another.
Again, I’ll cover FaceTime a bit later in the book, but just remember after you’ve gone through that chapter that you can select the FaceTime option when viewing a contact’s Info page.
