do you mean on your home screen? if you have a page with no apps on it, press and hold until your apps jiggle and some will appear with an x above them. first just do that and then press the home button. if that does not work, do the first step again and then move on app onto your last page. press home button. press and hold again. move the app back. that should do it. your iPod does not realize you have no apps on the last page. if none of that works, i have no idea.
