Unlike the Afaria method of device provisioning, Apple provisioning is primarily performed by developers at the end of their development cycle, with some Sybase Control Center configuration performed by the administrator, and some device setup by the device user. Apple Push Notification Service (APNS) supports user notifications on iPhone devices.
iOS devices do not require a runtime or a client; only the application must be deployed to the device. The lack of a runtime allows users to self-manage their devices: device users download application files to their iOS devices and synchronize updates as required.
