OK, now we're at the stage of linking it up. Right click the project and select "Options". In the Project Options dialogue go down to the "Build" section and select the "iPhone Application". Here you'll see the "Application Icon" option where you can select the icon from the list.

以下にて設定。
プロジェクト＞オプション＞Build>iPhoneApplication＞Application Icon
3G/3GS用は"Icon.png"
4は"Icon@2x.png"とすべし。
Build Action を"Resource"とすべし。
