OK, I have resolved this very easily. Even I have stated my nib files in pList, somehow only iPad nib file was displayed as Main Interface when I look at the project target summary. So I put there the one that should be there and now it is working on IPod as well.

It looks like you're trying to get mobile type info (IMEI etc presumably), and there won't be any on an iPod Touch.

I'd look for 2 posible causes: iOS versions, phone specific code.

For the first option, I'd try to use the iphone simulator on different versions (you can change that on the simulator itself). If that doesn't look like the problem, then try to search for a place in your code where you might use phone specific things, like trying to get the IMEI.
