Yet another important change for the Nokia Asha UI is icon style. Let’s start with the launcher icons!
The launcher icon you need to create and pack with your MIDlet (or Web app, for that matter) is 50×50 pixel square shaped icon. This icon will show on the activity screen. However, when you look at your icon on the Home screen you will notice that your icon has in some mystical way changed to the surround shape. This is because the phone trims the icon to the correct shape. You don’t need to worry about that. In any other aspect, than you should try out how your icon will look when trimmed.
