Help...Question about publishing Unity game on iPhone..

I have a iPod Touch G1, and I wanna put my game on it and run, so I built my game out and compiled in xCode, everything works fine. but in the end, I pressed the icon on my iTouch screen, Unity icon appeared for a second. then the program just shut down and jumped out. it seems that the program cannot run…

then I tried to run this on my simulator in xCode, it jumps out also…

and then, I tried the official example “OcclusionCulling” , still failed…

Can anyone help…I really need some…
my iPodTouch is Generation1 with iOS 3.1.3.

thx very much!!!

Quoting from some place I read before.

The iPhone simulator is pretty much useless because it does not simulate input from the iPhone and because it does not emulate performance you get on the iPhone. You simulate directly in Unity in game view and to test performance and optimize you publish to the iPhone.

And to do it from inside unity use - Unity Remote

About the app not running on iTouch gen 1 its not surprising. Gen 1 is just too slow to handle unity.
I ve read in places that you must atleast have gen 2
Though unity does not specify that but yea its just too much to handle with little processing
