Messages supports text messages with other SMS and MMS devices, and with other iOS devices using iMessage. With MMS and iMessage, you can also include photos, videos, and other info.

Use iMessage to send messages over Wi-Fi or cellular data connections to other iOS 5 users. You can see when the other person is typing, and let others be notifed when you’ve read their messages. Because iMessages are displayed on all of your iOS 5 devices logged in to the same account, you can start a conversation on one of your devices, then continue it on another device. iMessages are also encrypted.

Note:  SMS and MMS require a cellular connection, and may not be available in all areas. Cellular
data charges or additional fees may apply
