Given that there are many sizes and color depths for different phones (also for the same creator), I Application for all of them and after that, a proper icon is downloaded for the Phone D app.

Is there a way to change the MIDLet icon when the application is downloaded?

As far as I know there is no way to do this. You can force the user to upgrade an app and change the icon. Without the loss of content downloaded by the app, it can be done more user-friendly.
