In my latest release application, everything looks good on iOS4+, but not on iOS5 Beta. The only thing that is wrong is that the UIBarButtonSystemItemPageCurl is not shown on iOS5 devices. It shows an empty UIBarButtonItem with style Plain. It looks good in IB in XCode 4.1, will test on my work computer as well on the BETA XCode tomorrow. Does anyone know why this happens, or is this a bug in iOS5
