Samsung EPIC 4G :: Get Epic To Send "normal" Signal To Other Apps?

Got the Samsung Desk Dock for easy re-charging and using phone on nightstand. If I use the Samsung Desk Home app from the market, that app automatically detects that the phone is in the dock and runs the app. However, no other app is able to detect that the phone is docked, even with the Desk/Home app uninstalled (i.e. not the default). My understanding is that the phone should send a signal to Android if the device is being docked. Then Android sends a broadcast to all apps that the device has been docked. I have tested with two different apps which are designed to run upon the phone being docked and neither detects the phone being docked. Without the Samsung dock app loaded, there is no change when the phone is docked. It seems like only the Samsung app is capable of detecting docking. Am I missing something? How can I get the Epic to send out the "normal" signal to other apps upon being docked?
