Curl effect library for ipad/iphone

We need source code for curl effect library for ipad/iphone and a sample app with this effect to see how it works, with these features: 1. It should be an iBooks-like cone curl effect from top right corner of page 2. The library should not use any private API's (such as CAFilter's curl) 3. The library should consist of a view and a delegate, which provides all information about paging. The view must support both landscape and portrait orientation and work on both iphone and ipad. 4. We do not need zoom support for the view. It will be placed inside of scroll view and should not conflict with UIScrollView gestures. 5. The view must process correctly number of pages in any orientation. 6. All details in PM
