Send Message
Because you haven’t yet reached the chapters that cover the Mail and Messages apps, I’m not going to go into the Send Message option in much detail here. Instead, I’ll remind you in Chapter 7, “The Mail App,” and Chapter 10, where this button will come in handy.
Tapping the Send Message button opens a window that allows you to select a contact’s phone number, email address, or other type of account (such as Twitter) to launch the matching app that will let you contact your, uh, contact. Again, the selection you make from the list will decide what other iOS app opens to let you continue.
