problem in running a unity project in iphone unity

Hi all...I am new to iphone unity. I created a sample game of car racing in simple unity...

Now i want to create that same game in the iphone unity. but when i open that project in the iphone unity it is showing nothing in the scene view.

so tell me is it possible or not????

also i download a sample project from the unity website.. i want to control(play) that game with mouse and can i change that??

please please help!!!!

You have to load the 'Scene' in Unity. Once you have opened the project, go to File->Open Scene... then select the scene for your simple car racing game.
