Most demos were similar to my CodeCamp session with the exception of the WCF Demo.
Here is a summary of the demos:
SMSInterception – Demo showing how to intercept a message, automatically respond to a message and call back the sender of the message. Used the Cellular Emulator.
SNAPI – Demo showing some of the functionality of SNAPI, changing battery level, adding headset and detecting incoming calls.
WCFDispatch – Sample Dispatch application using Push Email for Windows Mobile and WCF Exchange Server Mail Transport for .NETCF 3.5. There is a good article here on WCF for Compact Framework which I based WCFMessagingManger from, there is also a lot more info on WCF using Exchange. (Requires Smart Device Framework Community Edition)
