Sending multiple iPhone notifications. Local and Push Notification Programming Guide: Apple Push Notification Service. Apple Push Notification service (APNs for short) is the centerpiece of the push notifications feature.
It is a robust and highly efficient service for propagating information to iOS and OS X devices. Each device establishes an accredited and encrypted IP connection with the service and receives notifications over this persistent connection. If a notification for an application arrives when that application is not running, the device alerts the user that the application has data waiting for it. Software developers (“providers”) originate the notifications in their server software. The provider connects with APNs through a persistent and secure channel while monitoring incoming data intended for their client applications.
In addition to being a simple but efficient and high-capacity transport service, APNs includes a default quality-of-service component that provides store-and-forward capabilities. Apple Push Notification Services Tutorial: Part 2/2. Create a simple chat app with Apple Push Notification Services!

(Read more details on developing server-side SMS/MMS applications in "Build mobile messaging into your web apps. ") SMS/MMS messages have no awareness of the applications installed on the recipient's device.
