Well, I have:

		// Set the image for the image managed object.
		//UIImage *selectedImage = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
		UIImage *selectedImage = [info objectForKey:@"UIImagePickerControllerEditedImage"];	
		[recipe.image setValue:selectedImage forKey:@"obverse"];
		
		// Create a thumbnail version of the image for the recipe object.
		CGSize size = selectedImage.size;
		CGFloat ratio = 0;
		if (size.width > size.height) {
			ratio = 320.0 / size.width;
		} else {
			ratio = 320.0 / size.height;
		}
		CGRect rect = CGRectMake(0.0, 0.0, ratio * size.width, ratio * size.height);
		
		UIGraphicsBeginImageContext(rect.size);
		[selectedImage drawInRect:rect];
		recipe.thumbnailImage = UIGraphicsGetImageFromCurrentImageContext();
}

and

//mask images
- (UIImage*) maskImage:(UIImage *)image withMask:(UIImage *)maskImage {
	
	UIImage *testMaskImage = [UIImage imageNamed: @"mask.png"];
	CGImageRef maskRef = testMaskImage.CGImage;
	
	CGImageRef mask = CGImageMaskCreate(CGImageGetWidth(maskRef),
										CGImageGetHeight(maskRef),
										CGImageGetBitsPerComponent(maskRef),
										CGImageGetBitsPerPixel(maskRef),
										CGImageGetBytesPerRow(maskRef),
										CGImageGetDataProvider(maskRef), NULL, false);
	CGImageRef masked = CGImageCreateWithMask([image CGImage], mask);
	CGImageRelease(mask);
	UIImage* retImage= [UIImage imageWithCGImage:masked];
	CGImageRelease(masked);
	return retImage;
	
}

I tried to add:

UIImage *maskImage = [UIImage imageNamed:@"circlemask.png"];
UIImage *selectedImage = [info objectForKey:@"UIImagePickerControllerEditedImage"];	

UIImage *maskedImage = [self maskImage:selectedImage withMask:maskImage];

but it complains that "maskedImage" is unused and

- (UIImage*) maskImage:(UIImage *)image withMask:(UIImage *)maskImage {

doesn't seem to get called no matter what I do.
