Windows Phone Thoughts: SpeakerPhone Auto On 1.02 for Windows Mobile

"Auto On v1.02 will automatically turn on your speakerphone. While the application is running, when an incoming call is received, the speakerphone of your device will automatically turn ON when you receive the call. You can also automatically activate the speakerphone when you are making an outgoing call by checking the Outgoing ON in the menu."

If your device supports a speakerphone mode and you are in a situation where it would be handy for that to be turned on automatically when you answer, this app would come in handy. The app is free, but not yet final. In fact, before running it, you have to manually create 3 registry keys so it works properly. There are instructions on the site.
