[APP] An application to play sounds during a phone conversation - Windows Mobile Apps and Games

This program plays a .wav file during a phone call. It can play the sound on the earphone or the speakerphone.
I developed the program to inject a sound into a phone conversation but the results are disappointing (at least on my Diamond 2) because the sound on the other side is very weak and distorted.
It seems the microphone is very well isolated from the speakerphone or maybe some kind of active cancellation removes the output sound stream from the input sound stream.
Whatever, I release here the program. Maybe, it may work better on other phones or someone knows how efficiently couple the sound from speakerphone to mic.
Usage
Copy the .exe on your phone and run it (it requires .NET Compact Framework V2.x)
Select a .wav file using the Sound... button.
Test the sound using the Test button and regulate the volume using the + and - button.
If you want to start the sound on phone connection check the Wait for Phone option.
If you want the sound on the speakerphone check the option (this does not work if you use a wired or bluetooth headset).
Tap the Start button and place or receive a phone call: on phone line connection the sound should start playing. The sound keeps looping until call end.
Or, do not check the Wait for Phone option.
Place or receive a phone call.
When the phone line connection is established tap the Start button: the sound should start playing and keep playing until you tap Stop.
If you want the sound on the speakerphone you should activate it manually (long press green button on my phone).

Thanks! I will dload it and try it now!
Actualy, there has been such an application for Symbian phones that would give the option when the phone was ringing to choose what sound to start playing, with preloaded sounds like "traffic", "office meeting", "football" etc.
