Answer 1

You can use UI_USER_INTERFACE_IDIOM() to check whether the application is running on an iPad or an iPhone/iPod touch:

if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
    // Running on iPad
} else {
    // Running on iPhone or iPod touch
}

For more information on loading NIB files, read Apple's Resource Programming Guide on Nib Files. You may want to specifically check out the Loading Nib Files Programmatically section which shows how to programatiically load a NIB from within your code using NSBundle. You can then use this in conjunction with the above code to correctly load the proper NIB depending on which device you're runining on.
