Loading Unity on IOS as fast as possibly

Just finished my fancy loading animation today and then fired up my project at my ipjhone 3GS. I realised that instantiating UNITY takes about 6 seconds (uncached) and then my loading animation shown for about 3 secs, not running very smoothly (Its physcis and it loads the real game asyncronously while handling the loading screen)

Whats the simplest project I can load in order to reduce the time a user sees no movement?

load a picture of the app in scene 0, and then load async, it will appear the app’s just loaded then?
