UIModalTransitionStylePartialCurl support for iOS 3.0?

According to the iPhone doc this particular modal transition is available for iOS version 3.2 and up. Yet i know my phone (running 3.1.3 i think) can do this curling transition because of the Google Maps app.

Is there another way/trick to get this curling transition for iOS versions < 3.2 ?

Thanks!

The UIModalTransitionStylePartialCurl was a private API before 3.2. In 3.2 it was documented and made public.

I would think that if you link against SDK 4.1, but target 3.1.3 devices, the app won't be rejected by Apple.
