Scene loading on ipad2 takes long time

I finally built successfully on iPad yesterday.
But I found the first time loading took about 30 seconds, even I just have a cube in the scene.
To be more specific:

Unity Logo (about 30 seconds)
Then scene loaded
anyone has solutions ?

I am using Unity 3.5
iOS 5.1 on iPad2
Xcode 4.2 for Leopard

i have the same problem … if you got solution please share with me.

Actually I am having the same issue, but I already tried to just have a build with an empty scene and it still takes forever.
