If you go with the solution of using 2 xib files; in your initWithNibName() method simply make a call to super with the different nib name.

I would test on the original 480 height dimension rather than on the 568 height so that the larger xib file is selected when Apple releases a larger screen. In the future, at least the larger xib won't be letter-boxed as much as the smaller one.

// From MainView.m
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    CGSize result = [[UIScreen mainScreen] bounds].size;
    if(result.height == 480)
    {
        // iPhone Classic
        self = [super initWithNibName:@"MainView" bundle:nibBundleOrNil];
    }
    else
    {
        // iPhone 5 or maybe a larger iPhone ??
        self = [super initWithNibName:@"MainView5" bundle:nibBundleOrNil];
    }

    return self;
}
