I was surprised to discover that Smartphone has a completely different scheme for implementing their control panel. Configuration Manager, the entity that can accept over-the-air device configuration requests, can also accept requests from the Control Panel Engine. Transactions between the Control Panel Engine and the Settings UI are performed with XML queries, and the resultant XML file is sent back to Configuration Manager and the request is routed to the appropriate Configuration Service Provider to be serviced. So adding a new item to the Settings menu on Smartphone is a little more esoteric, since it’s not documented in the SDK.
