AIR for iOS device compatibility

Question

When I tried to test a game I have been making in Flash on my iPod Touches (I tried it on 1st and 2nd generation ones), iTunes tells me that it is not compatible with either iPods when I try to sync the devices. However, a few weeks ago, I got a simple "Hello World"-type app I compiled with AIR for iOS to work on the 2nd gen iPod Touch, but when I tried it again today, I had the same problem as I did with my game.
It doesn't make sense that an AIR for iOS app would work one time and not another, so I have serious doubts that it is because they are incompatible with earlier iOS devices. I thought that I followed all the steps listed in order to test the apps on my devices, but there is certainly a chance that I did something wrong. Has anyone else had this problem? Does this mean that I am setting up my certificates incorrectly or doing something else wrong?

Multitouch.inputMode = MultitouchInputMode.GESTURE;
stage.addEventListener(TransformGestureEvent.GESTURE_ZOOM, f);
function f(event:TransformGestureEvent):void{
    mc.scaleX *= event.scaleX;
    mc.scaleY *= event.scaleY;
