Stuart, Have you made any more changes to this code? Also, do you have a photo of how this looks? I'm thinking of adding a pager control to my app--I use a UIPagerController in my iPhone version and am looking for something like the UIPagerControl (http://books.google.com/books?id=lFe0EwHUREEC&pg=PA125&lpg=PA125&dq=uipagercontrol&source=bl&ots=-SNjmXH5Z3&sig=Aa0tUicP1yWkcJ0cA8i8STg6_3w&hl=en&sa=X&ei=2yA3T8WzA8mEsALg-fSiAg&ved=0CC8Q6AEwAg#v=onepage&q=uipagercontrol&f=false)
