Edit: rebuilt the app from scratch, copying over all assets, and it seems to work fine on my iPod 4. These devices still are having the same issue: iPad 5.0 and iPhone 5.0, all sizes.
I did some more tests, and tried the app on all the simulators and on my iPod 4 (running iOS 6.1.3).
On the iPod 4, the app doesn't get past the "made with mmf" screen, and displays this information in xcode:
Code:
//
// main.m
// RuntimeIPhone
//
// Created by Francois Lionet on 08/10/09.

#import <UIKit/UIKit.h>
int main(int argc, char *argv[])
{
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
int retVal = UIApplicationMain(argc, argv, nil, @"RuntimeIPhoneAppDelegate");
[pool release];
return retVal;
}
(the bold line is highlighted with the information "Thread 1: signal SIGABRT" on the right)
and this information is displayed below, in the "output" box:

The app works fine in these simulators:
iPad 5.1 (non-retina), iPad 5.1 (retina), iPhone 6.1 (retina 4"), iPad 6.1 (non-retina)
And has issues in these simulators (some have different outputs, none will start the game past the "made with mmf" screen):
iPad 5.0, iPhone 5.0, iPhone 5.1, iPhone 5.1 (retina 3.5"), iPad 6.1 (retina), iPhone 6.1 (non-retina), iPhone 6.1 (retina 3.5") (see edit up top for update on these)
I'm so confused 
Here's another error output from the iPhone 5.1 simulator:
