iPhone: Blur UIImage

Question

In my iPhone application I have a black-and-white UIImage. I need to blur that image (Gaussian blur would do).

iPhone clearly knows how to blur images, as it does that when it draws shadows.

However I did not found anything related in the API.

Do I have to do blurring by hand, without hardware acceleration?
